Neoclassical compoundNeoclassical compounds are compound words composed from combining forms (which act as affixes or stems) derived from classical languages (classical Latin or ancient Greek) roots. Neo-Latin comprises many such words and is a substantial component of the technical and scientific lexicon of English and other languages, via international scientific vocabulary (ISV). For example, Greek bio- combines with Latin -graphy to form biography ("life" + "writing/recording").
International scientific vocabularyInternational scientific vocabulary (ISV) comprises scientific and specialized words whose language of origin may or may not be certain, but which are in current use in several modern languages (that is, translingually, whether in naturalized, loanword, or calque forms). The name "international scientific vocabulary" was first used by Philip Gove in Webster's Third New International Dictionary (1961). As noted by David Crystal, science is an especially productive field for new coinages.
Hybrid wordA hybrid word or hybridism is a word that etymologically derives from at least two languages. The most common form of hybrid word in English combines Latin and Greek parts. Since many prefixes and suffixes in English are of Latin or Greek etymology, it is straightforward to add a prefix or suffix from one language to an English word that comes from a different language, thus creating a hybrid word. Hybridisms were formerly often considered to be barbarisms. Antacid – from Greek ἀντι- () 'against' and Latin acidus 'acid'; this term dates back to 1732.
InterlinguaInterlingua (ɪntərˈlɪŋɡwə; ISO 639 language codes ia, ina) is an international auxiliary language (IAL) developed between 1937 and 1951 by the American International Auxiliary Language Association (IALA). It ranks among the most widely used IALs and is the most widely used naturalistic IAL – in other words, those IALs whose vocabulary, grammar, and other characteristics are derived from natural languages, rather than being centrally planned.
Compound (linguistics)In linguistics, a compound is a lexeme (less precisely, a word or sign) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. Compounding occurs when two or more words or signs are joined to make a longer word or sign. A compound that uses a space rather than a hyphen or concatenation is called an open compound or a spaced compound; the alternative is a closed compound.
