What does melodic imitation mean?

Melodic imitation in music refers to the repetition or restatement of a musical phrase, melody, or motive in a different voice or part of the composition usually after a slight delay or overlap. It involves the imitation of a musical idea by another voice, instrument, or section, often at a different pitch, octave, or with some variation. Melodic imitation creates a sense of continuity and development, and adds harmonic and textural interest to a musical composition.
