Laugh, giggle, snicker, titter, chuckle, guffaw, cachinnate.

What differences in human nature, conditions, and disposition are revealed by laughter!  If a person gives audible expression to mirth, gayety, or good-humor, the simplest word to apply to what he does is laugh.  But suppose a girl, with slight or insufficient provocation, engages in silly or foolish though perhaps involuntary laughter.  We should say she giggles.  Suppose a youngster is amused at an inappropriate moment and but partly suppresses his laughter; or suppose he wilfully permits the breaking forth of just enough laughter to indicate disrespect.  He snickers.  Suppose a person gives a little, light laugh; or more especially, suppose a crowd gives such an one as the result of slight, simultaneous amusement.  Our word now is titters.  Suppose we laugh low or gently or to ourselves.  We chuckle.  Suppose some one laughs loudly, boisterously, even coarsely, in a manner befitting a lumber camp rather than a drawing room.  That person guffaws.  Suppose a man engages in explosive and immoderate laughter.  He cachinnates.

Assignment for further discrimination:  chortle, roar.

Second assignment:  Name all the words you can that designate inaudible laughter (for example, smile, smirk, grin).
