LexiconA lexicon (plural: lexicons, rarely lexica) is the vocabulary of a language or branch of knowledge (such as nautical or medical). In linguistics, a lexicon is a language's inventory of lexemes. The word lexicon derives from Greek word λεξικόν (lexikon), neuter of λεξικός (lexikos) meaning 'of or for words'. Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar, a system of rules which allow for the combination of those words into meaningful sentences.
VyākaraṇaVyākaraṇa (व्याकरण, ˈʋjaːkɐrɐɳɐ) refers to one of the six ancient Vedangas, ancillary science connected with the Vedas, which are scriptures in Hinduism. Vyākaraṇa is the study of grammar and linguistic analysis in Sanskrit language. Pāṇini and Yāska are the two celebrated ancient scholars of Vyākaraṇa; both are dated to several centuries prior to the start of the common era, with Pāṇini likely from the fifth century BCE. Pāṇini's Aṣṭādhyāyī is the most important surviving text of the Vyākaraṇa traditions.
LoanwordA loanword (also a loan word, loan-word, or borrowing) is a word at least partly assimilated from one language (the donor language) into another language (the recipient language, also called the target language). This is in contrast to cognates, which are words in two or more languages that are similar because they share an etymological origin; and calques, which involve translation. Loanwords from languages with different scripts are usually transliterated (between scripts), but they are not translated.
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.
Folk etymologyFolk etymology (also known as popular etymology, analogical reformation, reanalysis, morphological reanalysis or etymological reinterpretation) is a change in a word or phrase resulting from the replacement of an unfamiliar form by a more familiar one. The form or the meaning of an archaic, foreign, or otherwise unfamiliar word is reinterpreted as resembling more familiar words or morphemes. The term folk etymology is a loan translation from German Volksetymologie, coined by Ernst Förstemann in 1852.
