acrimonious, dogged, ill-natured, splenetic,
churlish, gloomy, severe, sulky,
crabbed, gruff, snappish, sullen,
crusty, ill-humored, sour, surly.

The _sullen_ and _sulky_ are discontented and resentful in regard to
that against which they are too proud to protest, or consider all
protest vain; _sullen_ denotes more of pride, _sulky_ more of resentful
obstinacy. The _morose_ are bitterly dissatisfied with the world in
general, and disposed to vent their ill nature upon others. The _sullen_
and _sulky_ are for the most part silent; the _morose_ growl out bitter
speeches. A _surly_ person is in a state of latent anger, resenting
approach as intrusion, and ready to take offense at anything; thus we
speak of a _surly_ dog. _Sullen_ and _sulky_ moods may be transitory;
one who is _morose_ or _surly_ is commonly so by disposition or habit.

MOTION.

Synonyms:

act, change, movement, process, transition.
action, move, passage, transit,

_Motion_ is _change_ of place or position in space; _transition_ is a
passing from one point or position in space to another. _Motion_ may be
either abstract or concrete, more frequently the former; _movement_ is
always concrete, that is, considered in connection with the thing that
moves or is moved; thus, we speak of the _movements_ of the planets, but
of the laws of planetary _motion_; of military _movements_, but of
perpetual _motion_. _Move_ is used chiefly of contests or competition,
as in chess or politics; as, it is your _move_; a shrewd _move_ of the
opposition. _Action_ is a more comprehensive word than _motion_. We now
rarely speak of mental or spiritual _motions_, but rather of mental or
spiritual _acts_ or _processes_, or of the laws of mental _action_, but
a formal proposal of _action_ in a deliberative assembly is termed a
_motion_. Compare ACT.

Antonyms:

immobility, quiescence, quiet, repose, rest, stillness.
