Is it ensure, insure, or assure?
Old English eom "to be, to remain," (Mercian eam, Northumbrian am), from PIE *esmi- (cf. Old Norse emi, Gothic im, Hittite esmi, Old Church Slavonic jesmi, Lithuanian esmi), from root *es-, the S-ROOT, which also yielded Greek esti-, Latin est, Sanskrit as-, and German ist.
In Old English it existed only in present tense, all other forms being expressed in the W-BASE (see were, was). This cooperative verb is sometimes referred to by linguists as *es-*wes-. Until the distinction broke down 13c., *es-*wes- tended to express "existence," with beon meaning something closer to "come to be" (see be).
Old English am had two plural forms: 1. sind/sindon, sie and 2. earon/aron The s- form (also used in the subjunctive) fell from use in English in the early 13c. (though it continues in German sind, the 3rd person plural of "to be") and was replaced by forms of be, but aron (aren, arn, are, from Proto-Germanic *ar-, probably a variant of PIE root *es-) continued, and as am and be merged it encroached on some uses that previously had belonged to be. By the early 1500s it had established its place in standard English. Art became archaic in the 1800s.
Old English beon, beom, bion "be, exist, come to be, become, happen," from Proto-Germanic *biju- "I am, I will be." This "b-root" is from PIE root *bheue- "to be, exist, grow, come into being," and in addition to the words in English it yielded German present first and second person singular (bin, bist, from Old High German bim "I am," bist "thou art"), Latin perfective tenses of esse (fui "I was," etc.), Old Church Slavonic byti "be," Greek phu- "become," Old Irish bi'u "I am," Lithuanian bu'ti "to be," Russian byt' "to be," etc. It also is behind Sanskrit bhavah "becoming," bhavati "becomes, happens," bhumih "earth, world."
The modern verb to be 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 Modern English 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 Old English was:
|1st pres.||ic eom|
|2nd pres.||þu eart|
|3rd pres.||he is|
|1st pret.||ic wæs||we wæron|
|2nd pret.||þu wære||ge waeron|
|3rd pret.||heo wæs||hie wæron|
|1st pret. subj.||ic wære||we wæren|
|2nd pret. subj.||þu wære||ge wæren|
|3rd pret. subj.||Egcferð wære||hie wæren|

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
