Middle English, dwarf.(American Heritage® Dictionary of the English Language, Fourth Edition)
The word is often used in the phrase "merry as a grig". The word is of uncertain origin, though various theories have been suggested, such as a corruption of "merry as a cricket" or "merry as a Greek", as in Shakespeare's Troilus and Cressida: "Then she's a merry Greek indeed." Johnson suggested that the word originally meant "anything below the natural size" (compare Swedish "krik" and Scottish "crick"). (Wiktionary)
