A variant or diminutive form of goglet; a small water vessel, typically made of porous earthenware, used for cooling water by evaporation.
Possibly from Hindi 'gular' through English colonial contact in India; the '-et' is a diminutive suffix, making it mean 'small guggle-vessel'.
In India, people discovered that porous clay vessels called gugglets could cool water through evaporation—a technology so effective that colonizers brought the word back to English where it became confused with related terms.
