▪ I. and, n.
breath, animus: see ande.
▪ II. and, conj.1 formerly prep.
(ænd, ənd, famil. ən, (ə)n)
Forms: 1– and; also 1 end, ond, 2–5 ant, 3–7 an, 8–9 dial. an', 3–4 occas. a; but usually expressed by the compendium for L. et, in OE. {oeamp}, later &, & (‘And per se’), so that it is impossible to tell the full form intended.
[OE. shows two forms: (1) and, ǫnd(:—OTeut. *anda) OFris. anda, and, OS. ant, OHG. ant, Goth. anda-, and, ON. and-, prep. ‘against, fronting’; (2) ęnd(:—OTeut. *andi) OFris. ande, and, an, end, en, OHG. anti, enti, inti, unti, endi, indi, unde, MHG. unde, und, unt, mod.G. und, Du. en, conj.; cf. L. ante before, Gr. ἀντί against, Skr. (Vedic) antí over against, locative of antá ‘end, boundary, vicinity,’ hence ‘on the frontier of, abutting on, fronting, facing.’ From the idea of opposition, juxtaposition, or antithesis, the word was used in the Teut. langs. to express the mutual relation of notions and propositions. The general Teut. form of the conj. is *andi, of the prep. *and(a; in OE., with the early loss of ęnd, and (ǫnd) remained for both, but soon became obs. as prep., exc. in a few derivatives: see C. The levelling of OE. ǫnd, ęnd, under the single form and was no doubt helped by the fact that the conj. is nearly always unemphatic, so that the vowel is obscured and tends to sink to a mere voice glide ((ə)nd). From the same cause the final d has from early times been often dropped, as now universally in the dialects, and commonly in familiar speech: bread and butter = bread 'n butter. See also an conj.]

T. Watson 7 Sacr. xvi. 98 b, He that hath promysed pardone vnto vs, whensoeuer we conuerte, dothe not promise vnto vs longe lyfe and to lyue whyle to morowe.
C. conj. conditional, = if. [This was a common use of MHG. unde; the ON. enda (which Vigfusson thinks ‘probably identical’ with and, while Sievers would see in it a reduced form of enn þó, even though) approached this use, in the latter clause of a conditional premiss, as ‘ef þú þorir, enda sér þú nokkut at manni..’ ‘if thou darest, and (supposing that) thou art something of a man..’ (Vigf.). It has been suggested that the Eng. use was derived from that of Norse enda, but this is very doubtful. More probably the idiom arose in Eng. independently, as in MHG. It may have originated from ellipsis, as in the analogous use of so, e.g. ‘I'll cross the sea, so it please my lord’ (Shakes.); cf. ‘and it please’; or it may be connected with the introductory and in ‘And you are going?’ A direct development from the original prepositional sense, though à priori plausible, is on historical grounds improbable. Modern writers, chiefly since Horne Tooke, have treated this as a distinct word, writing it an, a spelling occas. found c1600, esp. in an' 't = and it. See an conj.]
