InterlingueInterlingue (interˈliŋɡwe; ISO 639 ie, ile), originally Occidental (oktsidenˈtaːl), is an international auxiliary language created in 1922 and renamed in 1949. Its creator, Edgar de Wahl, sought to achieve maximal grammatical regularity and natural character. The vocabulary is based on pre-existing words from various languages and a derivational system which uses recognized prefixes and suffixes. Many of Interlingue's derived word forms reflect those common to certain Western European languages, primarily the Romance languages, along with some Germanic vocabulary.
AdverbAn adverb is a word or an expression that generally modifies a verb, adjective, another adverb, determiner, clause, preposition, or sentence. Adverbs typically express manner, place, time, frequency, degree, level of certainty, etc., answering questions such as how, in what way, when, where, to what extent. This is called the adverbial function and may be performed by single words (adverbs) or by multi-word adverbial phrases and adverbial clauses. Adverbs are traditionally regarded as one of the parts of speech.
Agreement (linguistics)In linguistics, agreement or concord (abbreviated ) occurs when a word changes form depending on the other words to which it relates. It is an instance of inflection, and usually involves making the value of some (such as gender or person) "agree" between varied words or parts of the sentence. For example, in Standard English, one may say I am or he is, but not "I is" or "he am". This is because English grammar requires that the verb and its subject agree in person.
InterlinguisticsInterlinguistics, as the science of planned languages, has existed for more than a century as a specific branch of linguistics for the study of various aspects of linguistic communication. Interlinguistics is a discipline formalized by Otto Jespersen in 1931 as the science of interlanguages, i.e. contact languages tailored for international communication. In more recent times, the object of study of interlinguistics was put into relation with language planning, the collection of strategies to deliberately influence the structure and function of a living language.
