IJ Digraph

IJ (lowercase ij; ; also encountered as Unicode compatibility characters IJ and ij) is a digraph of the letters ''i'' and ''j''. Occurring in the Dutch language, it is sometimes considered a ligature, or a letter in itself. In most fonts that have a separate character for ''ij'', the two composing parts are not connected but are separate glyphs, which are sometimes slightly kerned.

An ''ij'' in written Dutch usually represents the diphthong , similar to the pronunciation of in "pay", and is preserved in such Dutch spellings as the place-name IJsselmeer. In standard Dutch and most Dutch dialects, there are two possible spellings for the diphthong : ''ij'' and ''ei'', with no clear usage rules. To distinguish between the two, the ''ij'' is referred to as the ("long ''ij''"), the ''ei'' as ("short ''ei''") or simply ''E – I''. In certain Dutch dialects (notably West Flemish and Zeelandic) and the Dutch Low Saxon dialects of Low German, a difference in the pronunciation of ''ei'' and ''ij'' is maintained. Whether it is pronounced identically to ''ei'' or not, the pronunciation of ''ij'' is often perceived as difficult by people who do not have either sound in their native language.

The ''ij'' originally represented a 'long i'. It used to be written as ''ii'', as in Finnish and Estonian, but for orthographic purposes, the second ''i'' was eventually elongated, which is a reason why it is called . This can still be seen in the pronunciation of some words like (), and the etymology of some words in the Dutch form of several foreign placenames: Berlin and Paris are spelled and . Nowadays, the pronunciation mostly follows the spelling, and they are pronounced with . The ''ij'' is distinct from the letter '' y''. Particularly when writing capitals, Y used to be common instead of IJ in the past. That practice has long been deprecated, since 1804. In scientific disciplines such as mathematics and physics, the symbol ''y'' is usually pronounced ''ij'' in Dutch.

To distinguish the ''Y'' from ''IJ'' in common speech, however, ''Y'' is often called (meaning "Greek ''Y''"), a literal translation of ' (from French, with the stress on ''grec'': ) or alternatively called ''Ypsilon''. In modern Dutch, the letter ''Y'' occurs only in loanwords, proper nouns, or when deliberately spelled as Early Modern Dutch. The spelling of Afrikaans (a daughter language of early modern Dutch) has evolved in the exact opposite direction and ''IJ'' has been completely replaced by ''Y''.

However, the ancient use of Y in Dutch has survived in some personal names, particularly those of Dutch immigrants in the United States, Canada, Australia and New Zealand where as a result of anglicization, the ''IJ'' became a ''Y''. For example, the surname ' was often changed into ''Spyker'' and ''Snijder'' into '' Snyder''.

History

''IJ'' probably developed out of ''ii'', representing a long sound (which it still does in some cases, such as in the word ' and in several Dutch dialects). In the Middle Ages, the ''i'' was written without a dot in handwriting, and the combination ''ıı'' was often confused with ''u''. Therefore, the second ''i'' was elongated: ''ıȷ''. Later, the dots were added, albeit not in Afrikaans, a language that has its roots in Dutch. In this language ''y'' is used instead.

Alternatively, the letter J may have developed as a swash form of ''i''. In other European languages it was first used for the final ''i'' in Roman numerals when there was more than one ''i'' in a row, such as ''iij'' for "three", to prevent the fraudulent addition of an extra ''i'' to change the number. In Dutch, which had a native ''ii'', the "final ''i'' in a row elongated" rule was applied as well, leading to ''ij''.

Another theory is that ''IJ'' might have arisen from the lowercase ''y'' being split into two strokes in handwriting. At some time in the 15th or 16th century, this combination began to be spelled as a ligature ''ij''. An argument against this theory is that even in handwriting which does not join letters, ''ij'' is often written as a single sign.

Some time after the birth of this new letter, the sound which was now represented by ''ij'', in most cases, began to be pronounced much like ''ei'' instead, but words containing it were still spelled the same. Nowadays, ''ij'' in most cases represents the diphthong , except in the suffix ''-lijk'', where it is usually pronounced as a schwa. In one special case, the Dutch word ''bijzonder'', the (old) sound is correct standard pronunciation, although is more common and is also allowed.

In proper names, ''ij'' often appears instead of ''i'' at the end of other diphthongs, where it does not affect the pronunciation: ''aaij'', ''eij'', ''oeij'', ''ooij'' and ''uij'' are pronounced identically to ''aai'' , ''ei'' , ''oei'' , ''ooi'' and ''ui'' . This derives from an old orthographic practice (also seen in older French and German) of writing ''y'' instead of ''i'' after another vowel; later, when ''y'' and ''ij'' came to be seen as interchangeable, the spellings with ''ij'' came to be used. Spelling reforms and standardization have removed the redundant ''j''s in common words, but proper names continue to use these archaic spellings.

Status

As the rules of usage for the ''IJ'' differ from those that apply to the many other digraphs in the Dutch language—in some situations behaving more as a single ligature or letter than a digraph—the ''IJ'' is not only confusing to foreigners, but also a source of discussion among native speakers of Dutch. Its actual usage in the Netherlands and in Flanders (Belgium) sometimes differs from the official recommendations.

Official status

Both the Dutch Language Union and the consider the ''ij'' to be a digraph of the letters ''i'' and ''j''. The descriptive dictionary '' Van Dale Groot woordenboek van de Nederlandse taal'' states that ''ij'' is a "letter combination consisting of the signs i and j, used, in some words, to represent the diphthong ɛi."''Van Dale Groot woordenboek van de Nederlandse taal'': "lettercombinatie bestaande uit de tekens i en j, gebruikt om, in een aantal woorden, de tweeklank ɛi weer te geven" The ''Winkler Prins'' encyclopedia states that ''ij'' is the 25th letter of the Dutch alphabet, placed between ''X'' and ''Y''.
However, this definition is not generally accepted.

In words where ''i'' and ''j'' are in different syllables, they do not form the digraph ''ij''. In compound words, a hyphen is added, as in ''gummi-jas''.

Netherlands

In the Netherlands, ''IJ'' is often used as a ligature:

* In Dutch primary schools, ''ij'' used to be taught as being the 25th letter of the alphabet, and some primary school writing materials still list it as such. However, ''ij'' is according to Onze Taal not part of the Dutch alphabet and is usually sorted under the ''i'' as it is considered to consist of two letters.
* When a word starting with ''IJ'' is capitalised, the entire digraph is capitalised: , .
* On mechanical Dutch typewriters, there is a key that produces 'ij' (in a single letterspace, located directly to the right of the ''L''). However, this is not the case on modern computer keyboards.
* In many word puzzles, such as Lingo, ''ij'' fills one square, but in others, such as Scrabble, ''ij'' fills two squares.

Flanders

In Flanders (Belgium), ''IJ'' is generally described in schools as a combination of two separate characters.

* As in the Netherlands, words that begin with ''IJ'' (and that are the first word in a sentence) usually capitalise the entire pair: ''IJzer'', '' IJzertoren''.

Usage

Capitalisation

When a Dutch word starting with ''IJ'' is capitalised, the entire digraph is capitalised, as in ''IJsselmeer'' or ''IJmuiden''.

Support for this property in software is limited. Poorly localised text editors with autocorrect functionality may incorrectly convert the second of two initial capital letters in a word to lowercase; such improper spelling can thus be found in informal writing. Support on the internet is similarly inconsistent: Web pages styled with the CSS property text-transform: capitalize are specified to be handled with Unicode language-specific case mapping rules (content language being indicated with HTML language attributes, such as lang="nl" for Dutch), but support for language-specific cases is limited to Mozilla Firefox (version 14 and above) .

Collation

Dutch dictionaries since about 1850 invariably sort ''ij'' as an ''i'' followed by a ''j'', i.e. between ''ih'' and ''ik''. This is the preferred sorting by the Taalunie. On the other hand, some encyclopedias, like the ''Winkler Prins'', 7th edition, sort ''ij'' as a single letter positioned between ''x'' and ''y''.

Telephone directories as well as the Yellow Pages in the Netherlands (but not those in Belgium) sort ''ij'' and ''y'' together, as if they were the same, between ''x'' and ''z''. Thanks to this, surnames like ''Bruijn'' and ''Bruyn'' which sound the same (and even look similar), can be found in the same area. However, ''Bruin'', though it sounds the same as well, is placed with "Brui-" and not with "Bruy-".

Abbreviations

When words or (first) names are shortened to their initials, in the Netherlands a word or proper name starting with ''IJ'' is abbreviated to ''IJ''. For example, ''IJsbrand Eises Ypma'' is shortened to ''IJ. E. Ypma''. The digraph "ei" in "Eises", like other digraphs in Dutch, is shortened to one letter.

Stress

In Dutch orthography, ''ad hoc'' indication of stress can be marked by placing an acute accent on the vowel of the stressed syllable. In case of a diphthong or double vowel, both vowels should be marked with an acute accent; this also applies to the ''IJ'' (even though ''J'' by itself is not a vowel, the digraph ''IJ'' represents one distinct vowel sound). However, due to technical limitations the accent on the ''j'' is often omitted in electronic documents: "". Nevertheless, in Unicode it is possible to combine characters into a ''j'' with an acute accent — "" — though this might not be supported or rendered correctly by some fonts or systems. This ''j́'' is the combination of the regular (soft-dotted) ''j'' (U+006A) and the combining acute accent  ́ (U+0301). In fonts where the j́ combination is not supported, the tittle on the j may be accompanied by the acute, resulting in ȷ̇́ or similar. This may be avoided by using the dotless ȷ (U+0237) with acute  ́ (U+0301), resulting in ȷ́.

Spelling

can be spelled out in two ways, depending on whether the speller considers ''ij'' to be one letter or not:

* ''V – R – IJ – D – A – G''
* ''V – R – I – J – D – A – G''

Wide inter-letter spacing

When words are written with large inter-letter spacing, ''IJ'' is often, but not always, kept together. ''F r a n k r ij k'' or ''F r a n k r i j k''.

When words are written from top to bottom, with non-rotated letters, ''IJ'' is usually, but not always, kept together. Keeping it together is the preferred way.

Spelling of proper names

In Dutch names, interchangeability of ''i'', ''ij'' and ''y'' is frequent. Some names are changed unofficially for commercial reasons or by indifference:

* Johan Cruijff/Cruyff, former football player and manager
* Ruud van Nistelrooij/Nistelrooy, football player
* Piet Heijn/Heyn/Hein, a Dutch West India Company admiral
* Dirk Kuijt/Kuyt, football player
* Arie Luijendijk/Luyendyk, race-driver
* Spijker/Spyker, car manufacturer
* Anner Bijlsma/Bylsma, cellist

The Dutch football team of Feyenoord changed its name from the original "" to "" after achieving international successes. This was done as a reaction to foreign people often mispronouncing the name. The Feijenoord district in Rotterdam, the namesake of the football club maintains its original spelling.

Phonetic radio alphabet

In the Dutch phonetic radio alphabet, the codeword represents the ''IJ''. This is clearly different from the codeword ''Ypsilon'', which is used to represent the ''Y''. Dutch and Belgian armed forces use the official NATO phonetic alphabet, where "Y" is "Yankee" and "IJ" is spelled out "India Juliett".

Word games

In crossword puzzles (except for Scrabble – see next paragraph), and in the game Lingo, ''IJ'' is considered one letter, filling one square, but the ''IJ'' and the ''Y'' are considered distinct. In other word games, the rules may vary.

The Dutch version of Scrabble has a ''Y'' with a face value of eight. Some players used it to represent ''IJ'' or ''Y''. The recent Dutch version comes with an example game, which clearly indicates that ''Y'' is only ''Y'', and ''IJ'' should be composed of ''I'' and ''J''. In previous editions of Scrabble there was a single IJ sign.

In word games that make a distinction between vowels and consonants, ''IJ'' is considered to be a vowel, if it is considered one letter. Whether ''Y'' is a vowel or a consonant, is another matter of discussion, since ''Y'' can represent both a vowel or a (half-) consonant.

Technical details

Print and handwriting

In print, the letter ''ÿ'' (lowercase y with diaeresis) and ''ij'' look very different, but handwriting usually makes ''ÿ'', ''ij'' and ''Y'', ''IJ'' look identical. However, since ''y'' occurs only in loanwords, the letter ''ÿ'' is extremely rare (if not altogether nonexistent) in Dutch.

The ''long ij'' extends below the baseline and so is written with a long stroke. It is often written as a single sign, even in handwriting that does not join letters.

On some road signs in the Netherlands, ''IJ'' appears as a single glyph formed like a ''U'' with a break in the left-hand stroke.

Braille

Dutch Braille, which is used in the Netherlands, has represented by , which represents in other varieties of Braille. is written as .

In Belgium, French Braille is used, in which is written simply as + : .

Encoding

The Dutch ''ij'' is not present in the ASCII code, nor in any of the ISO 8859 character encodings. Therefore, the digraph is most often encoded as an ''i'' followed by a ''j''. The ligature is present as a national-use character within the Dutch version of ISO 646, one implementation of which is of DEC's National Replacement Character Set (NRCS) aka code page 1102, and it also existed in the Atari ST character set (but not in the GEM character set for PCs) as well as in the Lotus Multi-Byte Character Set (LMBCS). It is also present in Unicode in the Latin Extended-A range as and .. These characters are considered compatibility-decomposable. They are included for compatibility and round-trip convertibility with legacy encodings, but their use is discouraged. Therefore, even with Unicode available, it is recommended to encode ''ij'' as two separate letters. Nonetheless, some fonts use this code point for the ligated form of IJ if it exists.

Keyboards

While Dutch typewriters usually have a separate key for lowercase ''ij'', Belgian typewriters do not.Most Belgian typewriters use the French AZERTY keyboard, though some may use the Belgian one instead; in both cases minus the peripheral keys to the left of the 1 and to the right of the ù, and of course all modifiers (including AltGr) other than Shift and CapsLock. The latter keyboard is used on Belgian computers. Neither of them knows ij or IJ except as i+j or I+J. In the Netherlands, a QWERTY computer keyboard layout is common. The standard US layout (often in " International Mode") is widely used, although a specific but rarely used Dutch variant (KBD143) does exist. In Belgium, a specific Belgian variant of AZERTY keyboard layout (KBD120) is widely used. None of these keyboards feature a key for ''ij'' or ''IJ''.

Not as a digraph

If the ''i'' and the ''j'' belong to different syllables, such as in the mathematical term (syllablised "bi‧jec‧tie"), words with old spelling (syllablised "mi‧ni‧jurk"), (syllablised "ski‧jas"), foreign placenames like , , or person names like , , , they do not form a ligature or a single letter. Earlier statements about sorting ''ij'' on par with ''y'', keeping ''ij'' together in the kerning of printed texts, the single square in crossword puzzles, etc., do not apply.
