Etymology in the context of "Historical linguistics"

The kithara (Greek: κιθάρα, romanized: kithára), Latinized as cithara, was an ancient Greek musical instrument in the yoke lutes family. It was a seven-stringed professional version of the lyre, which was regarded as a rustic, or folk instrument, appropriate for teaching music to beginners. As opposed to the simpler lyre, the cithara was primarily used by professional musicians, called kitharodes. In modern Greek, the word kithara has come to mean "guitar"; etymologically, the word guitar derives from kithara.

Doctrine (from Latin: doctrina, meaning 'teaching, instruction') is a codification of beliefs or a body of teachings or instructions, taught principles or positions, as the essence of teachings in a given branch of knowledge or in a belief system. The etymological Greek analogue is 'catechism'.

Often the word doctrine specifically suggests a body of religious principles as promulgated by a church. Doctrine may also refer to a principle of law, in the common-law traditions, established through a history of past decisions.

This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine. First, prefixes and suffixes, most of which are derived from ancient Greek or classical Latin, have a droppable vowel, usually -o-. As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr- + -o- + -logy = arthrology), but generally, the -o- is dropped when connecting to a vowel-stem (e.g. arthr- + -itis = arthritis, instead of arthr-o-itis). Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.

Choronym (from Greek: χώρα 'region' or 'country' and Greek: ὄνομα 'name') is a linguistic term that designates a proper name of an individual region or a country. The study of regional and country names is known as choronymy, or choronymics. Since choronyms are a subclass of toponyms, choronymic studies represent a distinctive subfield of toponymic studies and belong to the wider field of onomastic studies.

Choronymic studies are primarily focused on questions related to the origin (etymology) and meanings (semantics) of choronyms. Since names of regions and countries have great historical, cultural, political and social significance, the field of choronymic studies is closely related to sociolinguistic and ethnolinguistic studies.

The etymology of the name of Italy has been the subject of reconstructions by linguists and historians. Considerations extraneous to the specifically linguistic reconstruction of the name have formed a rich corpus of solutions that are either associated with legend (the existence of a king named Italus) or in any case strongly problematic (such as the connection of the name with the grape vine, vitis in Latin).

One theory is that the name derives from the word Italói, a term with which the ancient Greeks designated a tribe of Sicels who had crossed the Strait of Messina and who inhabited the extreme tip of the Italic Peninsula, near today's Catanzaro. This is attested by the fact that the ancient Greek peoples who colonized present-day Calabria, referred to themselves as Italiotes, that is, inhabitants of Italy. This group of Italian people had worshiped the simulacrum of a calf (vitulus, in Latin), and the name would therefore mean "inhabitants of the land of calves (young bulls)". In any case, it is known that in archaic times the name indicated the part located in the extreme south of the Italian Peninsula.

Pyrotechnics is the science and craft of creating fireworks, but also includes safety matches, oxygen candles, explosive bolts (and other fasteners), parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name comes from the Greek words pyr (πυρ; 'fire') and technikós (τεχνικός; 'artistic').

Improper use of pyrotechnics could lead to pyrotechnic accidents. People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians.

In historical linguistics, cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language.

Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. It can also happen that words which appear similar, or identical, in different languages, are not cognate.
