ATTAIN.

Synonyms:

accomplish, arrive at, gain, master, reach,
achieve, compass, get, obtain, secure,
acquire, earn, grasp, procure, win.

A person may _obtain_ a situation by the intercession of friends, he
_procures_ a dinner by paying for it. _Attain_ is a lofty word, pointing
to some high or desirable result; a man _attains_ the mountain summit,
he _attains_ honor or learning as the result of strenuous and earnest
labor. Even that usage of _attain_ which has been thought to refer to
mere progress of time carries the thought of a result desired; as, to
_attain_ to old age; the man desires to live to a good old age; we
should not speak of his _attaining_ his dotage. One may _attain_ an
object that will prove not worth his labor, but what he _achieves_ is in
itself great and splendid; as, the Greeks at Marathon _achieved_ a
glorious victory. Compare DO; GET; REACH.

Antonyms:

abandon, fail, forfeit, give up, let go, lose, miss.

was found in a sitting _posture_, where the _posture_ is thought of as
assumed in life, or as, at first glance, suggesting life. A _posture_ is
assumed without any special reference to expression of feeling; as, an
erect _posture_, a reclining _posture_; _attitude_ is the _position_
appropriate to the expression of some feeling; the _attitude_ may be
unconsciously taken through the
