Encircle comes from en- ('in, to put in') + circle (from Latin circulus, diminutive of circus 'ring, circle'). Morphologically, the form is compositional, with the named elements combining to produce the modern spelling and sense. In present use, it is used as a verb meaning "to form a circle around; surround", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as encirclement and encircled and related forms such as circle, circular, and circuit, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin circulus and Latin circus, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood is marked by surround, encompass, ring, and gird on one side and contrasts such as release, free, and open on the other, locating the modern specialization without adding a new origin story.
