He writes a good hand (handwriting).
Death fell in showers (bullets).
The kettle boils (water).
The pen is mightier than the sword (intelligence vs. force).
=Synecdoche= occurs where the part is taken for the whole, the species
for the genus, the material for the thing made of it, where the person
is designated by the most conspicuous trait of his character or the
effect he produces.
Thus we may speak of “all hands being at work,” of so many “head” of
cattle.
=Climax=.--Climax, or the rhetorical ladder, is the arrangement of a
succession of words, or clauses, in such a way that the weakest may
stand first; and that each in turn may rise in importance and make a
deeper impression on the mind than that which preceded it.
Anti-climax reverses the order: this is often used in humorous writings.
