Abundant; plentiful; in great quantities; full; ample; furnishing full supplies. The tender heart is peace, and kindly pours its copious treasures forth in various converse.

Furnishing abundant matter; not barren; rich in supplies. The redemption of man is a copious’ subject of contemplation. Hail, Son of God, Savior of men! Thy name shall be the copious matter of my song.
