say verse if the composition is metrical.

_Point Blank_. "He fired at him point blank." This usually is intended
to mean directly, or at short range. But point blank means the point
at which the line of sight is crossed downward by the trajectory--the
curve described by the missile.

_Poisonous_ for _Venomous_. Hemlock is poisonous, but a rattlesnake is
venomous.

_Politics_. The word is not plural because it happens to end with s.

_Possess_ for _Have_. "To possess knowledge is to possess power."
Possess is lacking in naturalness and unduly emphasizes the concept of
ownership.

_Practically_ for _Virtually_. This error is very common. "It is
practically conceded." "The decision was practically unanimous." "The
panther and the cougar are practically the same animal." These and
similar misapplications of the word are virtually without excuse.

_Predicate_ for _Found_, or _Base_. "I predicate my argument on
universal experience." What is predicated of something is affirmed as
an attribute of it, as omnipotence is predicated of the Deity.

_Prejudice_ for _Prepossession_. Literally, a prejudice is merely a
prejudgment--a decision before evidence--and may be favorable or
unfavorable, but it is so much more frequently used in the latter
sense than in the former that clarity is better got by the other word
for reasonless approval.
