Intersperse derives from Latin interspersus, formed by combining the familiar prefix inter- ("between or among") with sparsus, the past participle of spargere, meaning "to scatter."

Intersperse is often followed by the preposition with, as in "a straggling street of comfortable white and red houses, interspersed with abundant shady trees" (from H. G. Wells' 1898 novel, The War of the Worlds).
