canticle

Canticle comes from Latin canticulum, a diminutive of canticum, meaning song. Behind it stands canere, to sing, the old Latin verb that also gave English chant and enchant through other paths. The smaller form did not always mean something trivial. It marked a song as a distinct piece.

In late antique Christianity, Latin canticum became the regular label for scriptural songs outside the Psalms. The Magnificat, the Benedictus, and the Nunc dimittis were chief examples. By the 4th and 5th centuries, these songs were fixed in the daily offices of the western church. A small song had become a formal liturgical unit.

Old French transmitted the word as canticle or cantique, and Middle English adopted canticle by the 14th century. English religious writing used it for biblical hymns and for the Song of Songs, long called Canticles in some traditions. The word therefore carried both a narrow liturgical sense and a broader scriptural one. Context decided which meaning was active.

Modern English still uses canticle chiefly in religious settings. It names a hymn-like biblical text, usually sung or recited in worship, and it can also refer to a sacred song modeled on that tradition. The diminutive origin still peeks through the form. A canticle is a song made formal by devotion.
