confoundyoudaoicibaDictYouDict[confound 词源字典]
confound: [13] Latin confundere literally meant ‘pour together’; it was a compound verb formed from the prefix com- ‘together’ and fundere ‘pour’ (source of English found ‘melt’ and fuse). This sense was later extended figuratively to ‘mix up, fail to distinguish’, a meaning which passed via Old French confondre into English. Meanwhile, the Latin verb’s past participle, confusus, came to be used as an adjective; in Old French this became confus, which English acquired in the 14th century as confuse.

This was soon assimilated to the normal pattern of English past participial adjectives as confused, from which the new verb confuse, was coined.

foundyoudaoicibaDictYouDict
found: Aside from the past form of find, there are two distinct words found in English. Found ‘establish’ [13] comes via Old French fonder from Latin fundāre, a derivative of fundus ‘bottom’ (which, like English bottom, goes back ultimately to Indo-European *bhud- or *bhund-). The Latin words also gave English founder, fund and fundamental. Found ‘melt’ [14], which is now mainly represented by the derived foundry [17], comes via Old French fondre from Latin fundere ‘pour, melt’.

This goes back to Indo-European *ghud-, *gheud-, from which English also gets ingot. Amongst related forms in English are (from French fondre) font, fondant, and fondu, (from Latin fundere) funnel, (from the Latin past participle fūsus) fuse and fusion, and (from *fud-, the immediate root of Latin fundere) futile [16], which etymologically means ‘that pours away’, hence ‘useless’.

funnel: [15] Etymologically, a funnel is something used for ‘pouring in’. The word comes via Provençal fonilh from Latin infundibulum ‘funnel’. This was a derivative of infundere ‘pour in’, a compound verb formed from in- ‘in’ and fundere ‘pour’ (source of English found ‘melt’, foundry, and fuse).

fuseyoudaoicibaDictYouDict
fuse: English has two distinct words fuse. The noun, ‘igniting device’ [17], comes via Italian fuso from Latin fūsus ‘spindle’, a word of unknown origin. Its modern application comes from the fact that the long thin shape of the original gunpowder-filled tubes used for setting off bombs reminded people of spindles. The Vulgar Latin diminutive form of fūsus, *fūsellus, gave French fuseau ‘spindle’, which is the ultimate source of English fuselage [20] (etymologically, ‘something shaped like a spindle’).

The verb fuse ‘melt’ [17] probably comes from fūsus, the past participle of Latin fundere ‘pour, melt’ (source of English found, foundry, and fusion [16]).

refuseyoudaoicibaDictYouDict
refuse: [14] Refuse comes via Old French refuser from an unrecorded Vulgar Latin *refūsāre. It is not altogether clear where this came from, for it has no direct Latin antecedent. One theory is that it represents a blend of Latin recūsāre ‘refuse’ (source of English recusant [16]), a compound verb based on causa ‘cause’, and refūtāre ‘rebut’ (source of English refute [16]), a compound verb based on the element *fūt-, found also in English confute [16].

But another long-established school of thought derives it from refūsus, the past participle of Latin refundere ‘pour back’ (source of English refund [14]) – the underlying notion being of something ‘poured back’ or ‘rejected’. The noun refuse ‘rubbish’ [15] probably comes from Old French refus ‘refusal’, a derivative of refuser ‘refuse’.

confound (v.)youdaoicibaDictYouDict
c. 1300, "make uneasy, abash," from Anglo-French confoundre, Old French confondre (12c.) "crush, ruin, disgrace, throw into disorder," from Latin confundere "to confuse," literally "to pour together, mix, mingle," from com- "together" (see com-) + fundere "to pour" (see found (v.2)).

The figurative sense of "confuse, fail to distinguish, mix up" emerged in Latin, passed into French and thence into Middle English, where it is mostly found in Scripture; the sense of "destroy utterly" is recorded in English from c. 1300. Meaning "perplex" is late 14c. The Latin past participle confusus, meanwhile, became confused (q.v.).
confused (adj.)youdaoicibaDictYouDict
early 14c., "discomfited, routed, defeated" (of groups), serving at first as an alternative past participle of confound, as Latin confusus was the past participle of confundere "to pour together, mix, mingle; to join together;" hence, figuratively, "to throw into disorder; to trouble, disturb, upset." The Latin past participle also was used as an adjective, with reference to mental states, "troubled, embarrassed," and this passed into Old French as confus "dejected, downcast, undone, defeated, discomfited in mind or feeling," which passed to Middle English as confus (14c.; for example Chaucer's "I am so confus, that I may not seye"), which then was assimilated to the English past participle pattern by addition of -ed. Of individuals, "discomfited in mind, perplexed," from mid-14c.; of ideas, speech, thought, etc., from 1610s. By mid-16c., the word seems to have been felt as a pure adj., and it evolved a back-formed verb in confuse. Few English etymologies are more confused.
