EXTEMPORANEOUS.

Synonyms:

extemporary, impromptu, offhand,
extempore, improvised, unpremeditated.

_Extemporaneous_, originally signifying _of_ or _from the time_ or
_occasion_, has come to mean done or made with but little (if any)
preparation, and is now chiefly applied to addresses of which the
thought has been prepared, and only the language and incidental
treatment left to the suggestion of the moment, so that an
_extemporaneous_ speech is understood to be any one that is not read or
recited; _impromptu_ keeps its original sense, denoting something that
springs from the instant; the _impromptu_ utterance is generally brief,
direct, and vigorous; the _extemporaneous_ speech may chance to be
prosy. _Offhand_ is still more emphatic as to the readiness and freedom
of the utterance. _Unpremeditated_ is graver and more formal, denoting
absolute want of preparation, but is rather too heavy a word to be
applied to such apt, ready utterance as is generally designated by
_impromptu_.

Antonyms:

elaborated, premeditated, prepared, read, recited, studied, written.

EXTERMINATE.

Synonyms:

annihilate, eradicate, overthrow, uproot,
banish, expel, remove, wipe out.
destroy, extirpate, root out,

_Exterminate_ (L. _ex_, out, and _terminus_, a boundary) signified
primarily to drive beyond the bounds or limits of a country; the word is
applied to races of men or animals, and is now almost exclusively used
for removal by death; individuals are now said to be _banished_ or
_expelled_. _Eradicate_ (L. _e_, out, and _radix_, root) is primarily
applied to numbers or groups of plants which it is desired to remove
effectually from the soil; a single tree may be _uprooted_, but is not
said to be _eradicated_; we labor to _eradicate_ or _root out_ noxious
weeds. To _extirpate_ (L. _ex_, out, and _stirps_, stem, stock) is not
only to _destroy_ the individuals of any race of plants or animals, but
the very stock, so that the race can never be restored; we speak of
_eradicating_ a disease, of _extirpating_ a cancer, _exterminating_ wild
beasts or hostile tribes; we seek to _eradicate_ or _extirpate_ all
vices and evils. Compare ABOLISH.
