When we denude something we strip it, like the branches of a tree. That seems a bit inverted to me, shouldn't it be to nude-something?


Prefixes can have multiple uses. In the case of denude:


late Middle English: from Latin denudare, from de- 'completely' + nudare 'to bare' (from nudus 'naked')

  • de ='completely' surprises me, though. Waiting to up vote. – Kris Nov 1 '12 at 6:26
  • In fact, that definition can decide the very validity of OP's question, and therefore if it should be closed. – Kris Nov 1 '12 at 6:28
  • @Kris some definitions of de- could mean intensity. – Fuhrmanator Nov 1 '12 at 7:13

Because sometimes Latin’s de- prefix meant something else than to strip something away or to undo or reverse the action of a verb. And so it also has come down to us as something else in English.

You were thinking of OED sense 6, so here are the OED’s senses 3–5 for de- to illustrate just a few of the other possibilities for that prefix:

3. Down to the bottom, completely; hence thoroughly on and on, away; also methodically, formally:

  • as dēclāmāre to shout away, declaim;
  • dēclārāre to make quite clear, declare;
  • dēnūdāre to strip quite bare, denude;
  • dēplōrāre to weep as lost, deplore;
  • dērelinquĕre to abandon completely, derelict;
  • dēspoliāre to spoil utterly, despoil.

b. To exhaustion, to the dregs:

  • as dēcoquĕre to boil down or away, decoct;
  • dēliquēscĕre to melt away, deliquesce.

4. In a bad sense, so as to put down or subject to some indignity:

  • as dēcipĕre to take in, deceive;
  • dēlūdĕre to make game of, delude;
  • dērīdēre to laugh to scorn, deride;
  • dētestārī to abominate, detest.

5. In late L., dēcompositus was used by the grammarians in the sense ‘formed or derived from a compound (word)’, passing later into that of ‘compounded over again, doubly or further compounded’; in this sense the word has in modern times been taken into chemistry, botany, etc. (see decomposite, decompound), and the prefix has been similarly used in other words, as decomplex, demixture.

There actually is a word that is constructed and means what you seem to be expecting of denude, and that is debare. Again per the OED:

trans. To strip down, make quite bare.

Hence † deˈbared ppl. a. So † deˈbare a., intensive of bare a.

  • 1567 Drant Horace’s Arte of Poetrie A ij, ― As wooddes are made debayre of leaues by turnyng of the yeare.
  • C. 1620 T. Robinson M. Magd. 223 ― Next her debared brests bewitch mine eyes.

As you see, it hasn’t been used much for quite some time. The OED labels it obsolete. Best stick with denude.


Though tchrist's answer is clearly correct, and the OED's sense 3 of de- governs the word denude, I was surprised to discover that Merriam-Webster's Eleventh Collegiate Dictionary doesn't provide a useful answer to the OP's question.

In its entry for denude, the Eleventh Collegiate gives the etymology as

ME, fr. L denuduare, fr. de- + nudus bare

But that dictionary's entry for de- is disappointingly incomplete:

de- prefix [ME, fr. AF de-, des-, partly fr. L de- down, from, away (fr. de, prep.) and partly fr. L dis-; L de akin to OIr di from OE to—more at dis-] 1 a : to do the opposite of [deactivate] b : reverse of [de-emphasis] 2 a : remove (a specified thing) from [delouse] b : remove (from) a specified thing [dethone] 3 : reduce [devalue] 4 : something derived from (a specific thing) [decompound] : derived from something (of a specified nature) [denominative] 5 : get off of (a specified thing) [detrain] 6 : having a a molecule characterized by the removal of one or more atoms (of a specified element) [**deoxy*-]

The only definition here that is even remotely related to the OED's clear and succinct "down to the bottom, completely" definition of de- is the fourth one, which, besides being worded rather vaguely (in effect, "something derived from something else of a particular kind" as a noun and "being derived from something of a particular kind" as an adjective), doesn't offer an associated verb form with a definition along the lines of "derive from (something of a specified nature) [denominate]."

Merriam-Webster's treatment of de- appears to leave unexplained such common de- verbs in English as default, delimit, denote, denude, and despoil.


No, it should not.

You are assuming that the verb denude has been constructed from the adjective nude.

That is not the case. The latin root is dēnūdō (and hence present infinitive dēnūdāre, perfect active dēnūdāvī, supine dēnūdātum.)

    You could cite a reference to be helpful. In fact, it is de + nude alright, just that nudere itself here has the meaning "to strip," derived in turn from nude, bare. See links at comment under OP. – Kris Nov 1 '12 at 5:48
