## Linguistic Note on Dipper Semigroup

The term **dipper semigroup** appears to have been coined by Seth Warner in an article exploring commutative inductive semigroups.

The name arises as a result of a suggestion by Seth Warner in his *Modern Algebra*, where he exploits the analogy by means of the shape of the Big Dipper constellation.
