1. down (from or to a place or state), as in DEPEND, DEPRESS;
2. off, away, aside, as in DECLINE, DETER;
3. down to the bottom or dregs, (hence) completely, thoroughly, as in L. dēcoquere (see DECOCTION); sometimes merely strengthening vbs., as in DECLARE, DENUDE;
4. with pejorative sense, as in DECEIVE, DERIDE;
5. by late L. grammarians used uniquely in dēcompositus derived from a compound word, further compounded, whence decomposite, decompound in chem., bot., etc.;
6. with the sense of undoing or reversing what is expressed by a vb., as in L. dēarmāre disarm, dēvelāre unveil, whence the formation of similar vbs. from sbs. to denote removal, as in DEFLOWER, DESPOIL; a similar notion was expressed by L. dis-, as in DISJOIN, and the use of this prefix, repr. in Rom. by des-, was widely extended, and through F. dé- (OF. des-) it became in Eng. adoptions identical with de- (cf. DEBATE, DEVELOP). Hence
7. as a living formative de- forms vbs., with corr. sbs., (a) denoting removal or riddance, as †debowel (XIV) disembowel, defrost (XX), DEHYDRATE; (b) with privative or reversive force mainly from late XVIII, as decentralize, decontrol, demagnetize.
