pusilamine is incorrectly written, and should be written as "coward" being its meaning:
It comes from the latin " pusillanimis pusillus animis " ( soul small, petty ) as opposed to " magnus animis " ( 41 great soul;. Etymologically it means of petty, little magnanimous spirit. Subsequently its meaning evolved to " coward, Miss value and willingness to confront the difficulties of life, fearful, timid, timid ".
