Methods and use

The most common methods in Western typography fall under the general technique of emphasis through a change or modification of font: ''italics'', boldface and . Other methods include the alteration of LETTER CASE and spacing as well as and *additional graphic marks*.


Font styles and variants

The human eye is very receptive to differences in "brightness within a text body." Therefore, one can differentiate between types of emphasis according to whether the emphasis changes the " blackness" of text, sometimes referred to as typographic color. A means of emphasis that does not have much effect on blackness is the use of ''
italics In typography, italic type is a cursive font based on a stylised form of calligraphic handwriting. Owing to the influence from calligraphy, italics normally slant slightly to the right. Italics are a way to emphasise key points in a printed tex ...

'', where the vertical orientation of each letter of the text is slanted to the left or right. With one or the other of these techniques (usually only one is available for any typeface), words can be highlighted without making them stand out much from the rest of the text (inconspicuous stressing). This is used for marking passages that have a different context, such as book titles, words from foreign languages, or internal dialogue. By contrast, a bold

makes letters of a text thicker than the surrounding text. Bold strongly stands out from regular text, and is often used to highlight keywords important to the text's content. For example, printed dictionaries often use boldface for their keywords, and the names of entries can conventionally be marked in bold.

This practice is often considered archaic in Latin script, and on computers is complicated since fonts are no longer issued by foundries with a standard baseline, so switching font may distort line spacing.

It was also often used in the past by American lawyers to flag important points in a legal text. Coinciding with the era of typewriter use, the practice became unnecessary with the advent of computerized text formatting, although it is still found on occasion in documents created by older lawyers.


Letter-spacing

Another means of emphasis is to increase the spacing between the letters, rather than making them darker, but still achieving a distinction in blackness. This results in an effect reverse to boldface: the emphasized text becomes lighter than its environment. This is often used in

'' is referred to as ''sperren'' in German, which could be translated as "spacing out": in typesetting with letters of lead, the spacing would be achieved by inserting additional non-printing slices of metal between the types, usually about an eighth of an em wide. On typewriters a full space was used between the letters of an emphasized word and also one before and one after the word. For black letter type boldface was not feasible, since the letters were very dark in their standard format, and on (most) typewriters only a single type was available. Although letter-spacing was common, sometimes different typefaces (e.g.

), underlining or colored, usually red ink were used instead. Since blackletter type remained in use in German speaking parts of Europe much longer than anywhere else, the custom of letter-spacing is sometimes seen as specific to German, although it has been used with other languages, including English. Especially in German, however, this kind of emphasis may also be used within modern type, e.g. where italics already serve another semantic purpose (as in linguistics) and where no further means of emphasis (e.g. small caps) are easily available or feasible. Its professional use today is very limited in German. This use of spacing is also traditionally found in Polish. German orthographic (or rather typographic) rules require that the mandatory blackletter ligatures are retained. That means, ''ſt'', ''ch'', ''ck'', and ''tz'' are still stuck together just as the letter '' ß'', whereas optional, additional ligatures like ''ff'' and ''ſi'' are broken up with a (small) space in between. Other writing systems did not develop such sophisticated rules since spacing was so uncommon therein. In

typography, it also used to be common to emphasize words using letter-spaced type. This practice for Cyrillic has become obsolete with the availability of Cyrillic italic and small capital fonts.


Underlining

Professional Western typesetting usually does not employ lines under letters for emphasis within running text, because it is considered too distracting. Underlining is, however, often used with typewriters, in handwriting and with some non-alphabetic scripts. It is also used for secondary emphasis, i.e. marks added by the reader and not the author.


Overlining

In Arabic, it is traditional to emphasize text by drawing a line over the letters. This is seen in the

Punctuation marks

Design

There are many designs. With both italics and boldface, the emphasis is correctly achieved by swapping into a different

with its bold or italic style. Professional typographic systems, including most modern computers, would therefore not simply tilt letters to the right to achieve italics (that is instead referred to as ''slanting'' or ''oblique''), print them twice or darker for boldface, or scale majuscules to the height of middle-chamber minuscules (like ''x'' and ''o'') for small-caps, but instead use entirely different typefaces that achieve the effect. The letter 'w', for example, looks quite different in italic compared to upright. As a result, typefaces therefore have to be supplied at least fourfold (with computer systems, usually as four font files): as regular, bold, italic, and bold italic to provide for all combinations. Professional typefaces sometimes offer even more variations for popular fonts, with varying degrees of blackness. Only if such fonts are not available should the effect of italic or boldface be imitated by algorithmically altering the original font. The modern Latin-alphabet system of fonts appearing in two standard weights, with the styles being regular (or "Roman"), italic, bold and bold italic is a relatively recent development, dating to the early twentieth century. Modern "Roman" type was developed around the 1470s, while italic type was developed around 1500 and was commonly used for emphasis by the early 17th century. Bold type did not arrive until the nineteenth century, and at first fonts did not have matching bold weights; instead a generic bold, sometimes a Clarendon or other kind of

. Some font families intended for professional use in documents such as business reports may also make the bold-style numbers take up the same width as the regular (non-bold) numbers, so a bold-style total lines up below the digits of the sum in regular style.

stated that "It is possible to write an entire word or phrase in capital letters in order to emphasize it", but adds that "On the whole, though, it is preferable to express emphasis, not with capital letters, but with italics." Many university researchers and academic journal editors advise not to use italics, or other approaches to emphasizing a word, unless essential, for example the Modern Language Association "discourages the use of italics in academic prose to emphasize or point, because they are unnecessary—most often, the unadorned words do the job without typographic assistance". Although emphasis is useful in speech, and so has a place in informal or journalistic writing, in academic traditions it is often suggested that italics are only used where there is a danger of misunderstanding the meaning of the sentence, and even in that case that rewriting the sentence is preferable; in formal writing the reader is expected to interpret and understand the text themselves, without the assumption that the precise intended interpretation of the author is correct. Italics are principally used in academic writing for texts that have been referenced, and for foreign language words. Similarly capitals and underlining have particular meanings, and are rarely used in formal writing for emphasis.
