arrantyoudaoicibaDictYouDict[arrant 词源字典]
arrant: [16] Arrant is an alteration of errant, as in knight errant. This originally meant ‘roaming, wandering’, but its persistent application to nouns with negative connotations, such as rogue and thief, gradually drove its meaning downwards by association, to ‘notorious’.

dipyoudaoicibaDictYouDict
dip: [OE] Like deep, dip comes ultimately from a Germanic base *d(e)up- ‘deep, hollow’. The derived verb, *dupjan, produced Old English dyppan, ancestor of modern English dip. It originally meant quite specifically ‘immerse’ in Old English, sometimes with reference to baptism; the sense ‘incline downwards’ is a 17th-century development.

grovelyoudaoicibaDictYouDict
grovel: [16] Old and Middle English had a suffix -ling, used for making adverbs denoting direction or condition. Few survive, and of those that do, most have had their -ling changed to the more logical-sounding -long (headlong and sidelong, for instance, used to be headling and sideling; darkling still hangs on – just – unchanged).

Among them was grovelling, an adverb meaning ‘face downwards’ based on the phrase on grufe ‘on the face or stomach’, which in turn was a partial translation of Old Norse á grúfu, literally ‘on proneness’ (grúfu may be related to English creep). It was not long before grovelling came to be regarded as a present participle, and the new verb grovel was coined from it.
