Incantation in poetry is language shaped to sound like a spell, chant, or ritual utterance. It usually relies on repetition, rhythm, and musical sounds to create a hypnotic or ceremonial effect. A poet may use incantatory language to suggest magic, prayer, superstition, or intense emotional power, even when no actual spell is involved.
Example
Dark water, turn;
bright ember, burn;
hear me now, and answer my call.
