Word Origin & History

be
O.E. beon, beom, bion "be, exist, come to be, become," from P.Gmc. *beo-, *beu-. This "b-root" is from PIE base *bheu-, *bhu- "grow, come into being, become," and in addition to the words in English it yielded German present first and second person sing. (bin, bist, from O.H.G. bim "I am," bist "thou
art"), L. perf. tenses of esse (fui "I was," etc.), O.C.S. byti "be," Gk. phu- "become," O.Ir. bi'u "I am," Lith. bu'ti "to be," Rus. byt' "to be," etc. It also is behind Skt. bhavah "becoming," bhavati "becomes, happens," bhumih "earth, world."

The modern verb in its entirety represents the merger of two once-distinct verbs, the "b-root" represented by be and the am/was verb, which was itself a conglomerate. Roger Lass ("Old English") describes the verb as "a collection of semantically related paradigm fragments," while Weekley calls it "an accidental conglomeration from the different Old English dial[ect]s." It is the most irregular verb in Mod.E. and the most common. Collective in all Germanic languages, it has eight different forms in Modern English:

BE (infinitive, subjunctive, imperative)
AM (present 1st person singular)
ARE (present 2nd person singular and all plural)
IS (present 3rd person singular)
WAS (past 1st and 3rd persons singular)
WERE (past 2nd person singular, all plural; subjunctive)
BEING (progressive & present participle; gerund)
BEEN (perfect participle).

The paradigm in O.E. was:

SING.PL.
1st pres.ic eom
ic beo
we sind(on)
we beoð
2nd pres.þu eart
þu bist
ge sind(on)
ge beoð
3rd pres.he is
he bið
hie sind(on)
hie beoð
1st pret.ic wæswe wæron
2nd pret.þu wærege waeron
3rd pret.heo wæshie wæron
1st pret. subj.ic wærewe wæren
2nd pret. subj.þu wærege wæren
3rd pret. subj.Egcferð wærehie wæren


The "b-root" had no past tense in O.E., but often served as future tense of am/was. In 13c. it took the place of the infinitive, participle and imperative forms of am/was. Later its plural forms (we beth, ye ben, they be) became standard in M.E. and it made inroads into the singular (I be, thou beest, he beth), but forms of are claimed this turf in the 1500s and replaced be in the plural. For the origin and evolution of the am/was branches of this tangle, see am and was.
"That but this blow Might be the be all, and the end all." ["Macbeth" I.vii.5]

be-
weak form of O.E. bi "by," probably cognate with second syllable of Gk. amphi, L. ambi and originally meaning "about" (see ambi-). This sense naturally drifted into intensive (cf. bespatter "spatter about," therefore "spatter very much"). Be- can also be privative (cf. behead),
causative, or have just about any sense required. The prefix was productive 16c.-17c. in forming useful words, many of which have not survived, e.g. bethwack "to thrash soundly" (1550s), betongue "to assail in speech, to scold" (1630s).

be

any of the hereditary occupational groups in early Japan (c. 5th-mid-7th century), established to provide specific economic services and a continuous inflow of revenue for the uji, or lineage groups. Each be was thus subsidiary to one of the uji into which all of Japanese society was then divided, and each kakibe, or worker, was effectively owned by the chief of his uji. Most be were agricultural units, producing rice for themselves and their superiors, but some engaged in crafts, fishing, or specific court functions. Those that acted as scribes, interpreters, diviners, or reciters for the court were national organizations; most other types of be were local
