Boskage (also "boscage") derives from Old French "boscage," from "bosc" (wood), and describes dense thickets or masses of trees and undergrowth. It is a distinctly literary and elevated word, found more often in poetry and poetic prose than in agricultural writing, chosen for its sound and romantic connotations rather than precision.
Spenser and Milton use boskage to create the atmosphere of enchanted woodland—
the dark, complex, entangling vegetation of romance and allegory, where
paths are lost and figures concealed. The word's slightly French character gives it
an exotic, courtly flavor that distinguishes it from homelier English words like copse or shaw. In pastoral poetry boskage marks the transition from the open, ordered world of fields into the wilder, more mysterious realm of woodland and its associated dangers and pleasures.
