- be
- be: [OE] There are four distinct components that go to make up the modern English verb be. The infinitive form be comes ultimately from an Indo-European base *bheu-, *bhu-, which also produced, by other routes, future and physical. Its Germanic descendant was *bu-, which signified on the one hand ‘dwell’ (from which we get booth, bower, byre, build, burly, byelaw, and the final element of neighbour), and on the other hand ‘grow, become’, which led to its adoption as part of the verb expressing ‘being’ (in Old English particularly with the future sense of ‘coming to be’). Am and is go back to the ancient Indo- European verb ‘be’, *es- or *s-, which has contributed massively to ‘be’ verbs throughout all Indo-European languages (third person present singulars Greek esti, Latin est, French est, German ist, Sanskrit ásti, Welsh ys, for example) The Indo-European first and third person singular forms were, respectively, ésmi and ésti.
For the present plural Old English used the related sind(on) (as found in Latin sunt, French sont, and German sind), but this died out in the 12th century, to be replaced by are, which comes from a Germanic base *ar- of unknown origin. From the same source is the now archaic second person singular art. The past tense forms was, were come ultimately from an Indo-European base *weswhich meant ‘dwell, remain’.
Related words in other Indo-European languages include Sanskrit vásati ‘dwell, remain’ and Gothic wisan ‘remain, continue’.
=> booth, bower, build, burly, byelaw, byre - quid pro quo
- 1560s, from Latin, literally "something for something, one thing for another," from nominative and ablative neuter singulars of relative pronoun qui "who" (see who) + pro "for" (see pro-) + quo, ablative of quid.
- -s (1)
- suffix forming almost all Modern English plural nouns, gradually extended in Middle English from Old English -as, the nominative plural and accusative plural ending of certain "strong" masculine nouns (such as dæg "day," nominative/accusative plural dagas "days"). The commonest Germanic declension, traceable back to the original PIE inflection system, it is also the source of the Dutch -s plurals and (by rhotacism) Scandinavian -r plurals (such as Swedish dagar).
Much more uniform today than originally; Old English also had a numerous category of "weak" nouns that formed their plurals in -an, and other strong nouns that formed plurals with -u. Quirk and Wrenn, in their Old English grammar, estimate that 45 percent of the nouns a student will encounter will be masculine, nearly four-fifths of them with genitive singular -es and nominative/accusative plural in -as. Less than half, but still the largest chunk.
The triumphs of -'s possessives and -s plurals represent common patterns in language: using only a handful of suffixes to do many jobs (such as -ing), and the most common variant squeezing out the competition. To further muddy the waters, it's been extended in slang since 1936 to singulars (such as ducks, sweets, babes) as an affectionate or diminutive suffix.
Old English single-syllable collectives (sheep, folk) as well as weights, measures, and units of time did not use -s. The use of it in these cases began in Middle English, but the older custom is preserved in many traditional dialects (ten pound of butter; more than seven year ago; etc.).
