英语中什么是be词

前缀be- = about,completely;to make ;to provide with

汉：来源于盎格鲁-撒克逊语，主要意思为"make"加强语气,作动词前缀。此外，前缀be还有介词"by"的含义，可构成名词、连词和副词。

在本族语词缀中，派生前缀be-的用法是较为复杂的，在古英语中，be-是介词by的弱读形式，它的基本意思是about或around,主要的引申义有completely（表示加强词义）。be-的属性有两种：1）介词性或副词性前缀。这时，它可以帮助构成像beside,between这样的介词，也可以加在动词上表示加强词义或构成及物动词。2）动词性前缀。这时，它可以加在名词或形容词上，意为to make 或to cause to be。如果加在物质名词上，be-还可以表示to provide with 的意思。在少数情况下，be-表示to make..off 的意思。

英：word-forming element with a wide range of meaning: "thoroughly, completely; to make, cause seem; to provide with; at, on, to, for," from Old English be- "on all sides" (also used to make transitive verbs and as a privative or intensive prefix), from weak form of Old English bi "by," probably cognate with second syllable of Greek amphi, Latin 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).
