What does be mean?
'Be' is the most fundamental verb in the English language, serving as the glue that holds sentences together. Its core function is as a copula, linking a subject to what it is: 'the night is cold', 'they are teachers'. It also expresses existence ('there is hope'), acts as an auxiliary to build continuous tenses ('she is reading') and passives ('it was written'), and appears in formal constructions expressing obligation or destiny ('we are to depart'). Remarkably irregular, 'be' supplies eight distinct forms — be, am, is, are, was, were, been, being — because English historically fused verbs from different roots into one suppletive system. No other English verb is used more frequently, and few words carry such grammatical weight. From philosophy ('to be or not to be') to everyday small talk, 'be' is indispensable, making it the single most important word for any learner of English to master.
To exist or have identity; to serve as a copula linking a subject with its predicate, and to function as an auxiliary verb forming progressive tenses and the passive voice.
"Whatever is meant to be will find its way."
Highly irregular: eight distinct forms including am, is, are, was, were, been, and being.
Rarely used as a noun, chiefly in philosophy and linguistics, referring to existence or the fact of being.
"Philosophers have long debated the nature of being itself."
In this sense 'being' is far more common than 'be'; the bare noun form appears mostly in technical or archaic contexts.
Shakespeare gave 'be' its most famous line over 400 years ago, but English borrowed its most essential verb from at least three different ancient roots stitched together.

Etymology of be
'Be' descends from Old English 'bēon', meaning to be, exist, or become, which traces back through Proto-Germanic to the Proto-Indo-European root *bʰuH-, meaning 'to grow' or 'to come into being'. This ancient root also produced the Greek 'physis' (nature), giving modern English words like 'physics' and 'physical'. Modern 'be' is part of a suppletive system: its present-tense forms 'am', 'is', and 'are' derive from different Indo-European roots than 'was' and 'were', meaning English speakers conjugate one concept using pieces of several ancient verbs.

How be is actually used
'Be' is highly irregular: it is the only English verb with eight distinct forms (be, am, is, are, was, were, been, being). In informal speech, contractions like 'I'm', 'you're', and 'it's' dominate, while some dialects use invariant 'be' for habitual actions (e.g. 'he be working'), a feature stigmatized despite being grammatically systematic. The subjunctive 'be' ('if need be') survives in formal registers.
