midwife: [14] A midwife is etymologically a ‘with-woman’. The mid- element represents the long extinct preposition mid ‘with’ (its Germanic relatives are still alive and well: German mit, Dutch met, and Swedish and Danish med). Wife preserves the original meaning of Old English wīf, ‘woman’. The idea underlying the word is that a midwife is ‘with’ a woman giving birth.

swift: [OE] The etymological meaning of swift appears to be ‘moving along a course’; ‘speed’ is a secondary development. It goes back ultimately to the prehistoric Germanic base *swei- ‘swing, bend’, which also produced English sweep, swivel [14], and the long defunct swive ‘copulate with’ (a descendant of Old English swīfan ‘move in a course’). Its use as a name for the fast-flying swallow-like bird dates from the 17th century.
=> sweep, swivel
wifeyoudaoicibaDictYouDict
wife: [OE] Wife originally meant simply ‘woman’, but the semantic restriction to ‘married woman’ began in the Old English period and has become more and more firmly established as the centuries have passed. Of the word’s Germanic relatives, German weib has largely been replaced by frau, and Dutch wijf, Swedish vif, and Danish viv are no longer front-line words. It is not known what its ultimate source was. A woman is etymologically a ‘wife-man’, that is, a ‘womanperson’, a ‘female-person’.

swift (n.)youdaoicibaDictYouDict
type of bird (several species of the family Cypselidæ, resembling swallows), 1660s, from swift (adj.) in reference to its swift flight. Regarded as a bird of ill-omen, if not downright demonic, probably for its shrill cry. The name earlier had been given to several small fast lizards (1520s).
wife (n.)youdaoicibaDictYouDict
Old English wif (neuter) "woman, female, lady," also, but not especially, "wife," from Proto-Germanic *wiban (cognates: Old Saxon, Old Frisian wif, Old Norse vif, Danish and Swedish viv, Middle Dutch, Dutch wijf, Old High German wib, German Weib), of uncertain origin, not found in Gothic.

Apparently felt as inadequate in its basic sense, leading to the more distinctive formation wifman (source of woman). Dutch wijf now means, in slang, "girl, babe," having softened somewhat from earlier sense of "bitch." German cognate Weib also tends to be slighting or derogatory and has been displaced by Frau.

The more usual Indo-European word is represented in English by queen/quean. Words for "woman" also double for "wife" in some languages. Some proposed PIE roots for wife include *weip- "to twist, turn, wrap," perhaps with sense of "veiled person" (see vibrate); and more recently *ghwibh-, a proposed root meaning "shame," also "pudenda," but the only examples of it would be the Germanic words and Tocharian (a lost IE language of central Asia) kwipe, kip "female pudenda."

The modern sense of "female spouse" began as a specialized sense in Old English; the general sense of "woman" is preserved in midwife, old wives' tale, etc. Middle English sense of "mistress of a household" survives in housewife; and the later restricted sense of "tradeswoman of humble rank" in fishwife. By 1883 as "passive partner in a homosexual couple." Wife-swapping is attested from 1954.
