In grammar, a contraction is a word formed by combining two or more words into a single word. For example, the contraction "don't" is formed by combining the words "do" and "not."

In physiology, a contraction is a movement of a muscle that makes it shorter and thicker. For example, when you flex your bicep, the bicep muscle contracts.

In medicine, a contraction is a strong rhythmic tightening of the uterus that occurs during labor. Contractions typically start out weak and infrequent, but they gradually become stronger and more frequent as labor progresses.
