The word "custom" originates from Old French costume, derived from Latin consuetudo (habit, practice), which combines con- (together) + suescere (to become accustomed). Over time, it evolved to emphasize habitual behavior or tradition. The morpheme cus- reflects the idea of habitual action, while -tom signifies a repeated practice. This duality captures the word’s core meaning: a socially ingrained pattern or norm.
