haircutting is a compound of hair (Old English hǣr) and cutting (gerund of cut), denoting the activity of cutting hair. Morphologically, the word is best read through the components named in the history, with the modern spelling preserving a compound structure rather than a single unanalyzable stem. In present English, the noun sense is "the activity of cutting hair", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as haircut and haircutter. Its semantic neighborhood includes barbering, hairdressing, and coiffure, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Old English hǣr.
