Moldboard
A plough or plow ( US; both ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses, but in modern farms are drawn by tractors. A plough may have a wooden, iron or steel frame, with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an ''aratrum''. Celtic peoples first came to use wheeled ploughs in the Roman era. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting. Ploughing and cultivating soil evens the content of the upper layer of soil, where most plant-feeder roots grow. Ploughs were initially powered by humans, but the use of farm ...

Tillage
Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. Examples of human-powered tilling methods using hand tools include shoveling, picking, mattock work, hoeing, and raking. Examples of draft-animal-powered or mechanized work include ploughing (overturning with moldboards or chiseling with chisel shanks), rototilling, rolling with cultipackers or other rollers, harrowing, and cultivating with cultivator shanks (teeth). Tillage that is deeper and more thorough is classified as primary, and tillage that is shallower and sometimes more selective of location is secondary. Primary tillage such as ploughing tends to produce a rough surface finish, whereas secondary tillage tends to produce a smoother surface finish, such as that required to make a good seedbed for many crops. Harrowing and rototilling often combine primary and secondary tillage into one operation. "Tillage" can also mean the lan ...

Ard (plough)
The ard, ard plough, or scratch plough is a simple light plough without a mouldboard. It is symmetrical on either side of its line of draft and is fitted with a symmetrical share that traces a shallow furrow but does not invert the soil. It began to be replaced in China by the heavy carruca turnplough in the 1st century, and in most of Europe from the 7th century. In its simplest form it resembles a Hoe (tool), hoe, consisting of a ''draft-pole'' (either composite or a single piece) pierced with a nearly vertical, wooden, spiked ''head'' (or ''stock'') which is dragged through the soil by draft animals and very rarely by people. The ard-head is at one end a ''stilt'' (handle) for steering and at the other a ''share'' (cutting blade) which gouges the surface ground. More sophisticated models have a composite pole, where the section attached to the head is called the ''draft-beam'', and the share may be made of stone or iron. Some have a cross-bar for handles or two separate stilts ...

Three-point Hitch
The three-point hitch (British English: three-point linkage) is a widely used type of hitch for attaching ploughs and other implements to an agricultural or industrial tractor. The three points resemble either a triangle, or the letter A. Three-point attachment is the simplest and the only statically determinate way of joining two bodies in engineering. A three-point hitch attaches the implement to the tractor so that the orientation of the implement is fixed with respect to the tractor and the arm position of the hitch. The tractor carries some or all of the weight of the implement. The other main mechanism for attaching a load is through a drawbar, a single point, pivoting attachment where the implement or trailer is not in a fixed position with respect to the tractor. The primary benefit of the three-point hitch system is to transfer the weight and resistance of an implement to the drive wheels of the tractor. This gives the tractor more usable traction than it would otherw ...

Welsh Language
Welsh ( or ) is a Celtic language family, Celtic language of the Brittonic languages, Brittonic subgroup that is native to the Welsh people. Welsh is spoken natively in Wales, by some in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "British", "Cambrian", "Cambric" and "Cymric". The Welsh Language (Wales) Measure 2011 gave the Welsh language official status in Wales. Both the Welsh and English languages are ''de jure'' official languages of the Welsh Parliament, the Senedd. According to the 2021 United Kingdom census, 2021 census, the Welsh-speaking population of Wales aged three or older was 17.8% (538,300 people) and nearly three quarters of the population in Wales said they had no Welsh language skills. Other estimates suggest that 29.7% (899,500) of people aged three or older in Wales could speak Welsh in June 2022. Almost half of all Welsh speakers consider themselves fluent Welsh speakers ...

Old Armenian
Classical Armenian (, in Eastern Armenian pronunciation: Grabar, Western Armenian: Krapar; meaning "literary anguage; also Old Armenian or Liturgical Armenian) is the oldest attested form of the Armenian language. It was first written down at the beginning of the 5th century, and all Armenian literature from then through the 18th century is in Classical Armenian. Many ancient manuscripts originally written in Ancient Greek, Persian, Hebrew, Syriac and Latin survive only in Armenian translation. Classical Armenian continues to be the liturgical language of the Armenian Apostolic Church and the Armenian Catholic Church and is often learned by Biblical, Intertestamental, and Patristic scholars dedicated to textual studies. Classical Armenian is also important for the reconstruction of the Proto-Indo-European language. Phonology Vowels There are seven monophthongs: * (ա), (ի), or schwa (ը), or open ''e'' (ե), or closed ''e'' (է), (ո), and (ու) (transcribed as ...

Proto-Indo-European Language
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. Its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. No direct record of Proto-Indo-European exists. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age. The majority of linguistic work during the 19th century was devoted to the reconstruction of PIE or its daughter languages, and many of the modern techniques of linguistic reconstruction (such as the comparative method) were developed as a result. PIE is hypothesized to have been spoken as a single language from 4500 BC to 2500 BC during the Late Neolithic to Early Bronze Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the original homeland of the Proto-Indo-Europeans may have been in the Pontic–Caspian steppe of ...

Vṛddhi
Vṛddhi (also rendered vr̥ddhi) is a technical term in morphophonology given to the strongest grade in the vowel gradation system of Sanskrit. The term is derived from Sanskrit ''vṛddhi'', , 'growth', from . Origins Vṛddhi itself has its origins in proto-vṛddhi, a process in the early stage of the Proto-Indo-European language originally for forming possessive derivatives of ablauting noun stems, with the meaning "of, belonging to, descended from".Clackson, §3.3. To form a vṛddhi-derivative, one takes the zero-grade of the ablauting stem (i.e. removes the vowel), inserts the vowel *''e'' in a position which does not necessarily match that of the original vowel, and appends an accented thematic vowel (or accents any existing final thematic vowel). For example: However, in a later stage of the language this appears to have extended to non-ablauting noun stems that already contained ''*e'', which would contract with the inserted vowel to form a lengthened ''*ē'': ...

Latin Language
Latin (, or , ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italy (geographical region), Italian region and subsequently throughout the Roman Empire. Even after the Fall of the Western Roman Empire, fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a fusional language, highly inflected language, with three distinct grammatical gender, genders (masculine, feminine, and neuter), six or seven ...
