Syn: To cover; cloak; hide; extenuate; conceal.

Usage: To {Palliate}, {Extenuate}, {Cloak}. These words, as
here compared, are used in a figurative sense in
reference to our treatment of wrong action. We cloak
in order to conceal completely. We extenuate a crime
when we endeavor to show that it is less than has been
supposed; we palliate a crime when we endeavor to
cover or conceal its enormity, at least in part. This
naturally leads us to soften some of its features, and
thus palliate approaches extenuate till they have
become nearly or quite identical. ``To palliate is not
now used, though it once was, in the sense of wholly
cloaking or covering over, as it might be, our sins,
but in that of extenuating; to palliate our faults is
not to hide them altogether, but to seek to diminish
their guilt in part.'' --Trench.
