Inflections: Plural pentominoes.

Origin: Formed within English, by compounding. Etymons: penta- comb. form, domino n.

Etymology: < penta- comb. form + -omino (in domino n.); coined by S. W. Golomb by analogy, taking the d- of domino (by an intentional false etymology) to represent either di- comb. form or duo- comb. form (see quots. 1954 at sense 1 and 1961 at sense 1).

1954 Amer. Math. Monthly 61 681 There are twelve distinct pentominoes.

1961 New Scientist 2 Nov. 316/2 A domino is formed from two adjacent squares: he [sc. Golomb] argues that practical needs and false etymology will justify our calling a square a monomino—whence we have a series monomino, domino, tromino, tetromino.., and Maestro pieces then become pentominoes.

1975 A. C. Clarke Imperial Earth xxiv. 173 He replaced the titanite cross in its setting between the F, N, U and V pentominoes.

1994 New Scientist 12 Nov. 49/1 Those weaned on Martin Gardener's Mathematical Games know Pentominoes as old friends. Five contiguous unit squares can form just 12 different shapes.

2. In plural. A board game or puzzle involving the rearrangement of plastic or wooden pentomino shapes.
