Laughter is the biological reaction of humans to moments or occasions of humor: an outward expression of amusement.

Laughter is subcategorised into various groupings depending upon the extent and pitch of the laughter: giggles, clicks (which can be almost silent), chortles, chuckles, hoots, cackles, sniggers and guffaws are all types of laughter.

Smiling may be considered a mild silent form of laughter.

Some studies indicate that laughter differs depending upon the gender of the laughing person: women tend to laugh in a more "sing-song" way, while men more often grunt or snort.
