Climax

Climax  is the arrangement of a series of ideas in
the order of increasing importance.
Examples:-
1. Simple, erect, severe, austere, sublime.
2. What a piece of work is man ! How noble in reason, how infinite in faculties ! In
action, how like an angel ! In apprehension, how like a god!

Anticlimax

Anticlimax is the opposite of Climax-a sudden descent from higher to
lower. It is chiefly used for the purpose of satire or ridicule.
Examples:-
1. Here thou, great Anna ! whom three realms obey,
Dost sometimes counsel take-and sometimes tea.
2. And thou, Dalhousie, the great god of war,
Lieutenant-Colonel to the Earl of Mar.
