saw-toothed

the compound adjective 'saw-toothed' is a modern english formation that vividly describes a serrated edge by combining two concrete nouns. the first element, 'saw', originates from the old english 'sagu', referring to the cutting tool known for its jagged, tooth-like blade. the second element, 'tooth', from old english 'tōþ', is used metaphorically to describe any pointed projection, a sense extension found in words like 'cogwheel' or 'comb'. the adjectival suffix '-ed' is appended, a productive pattern in english for creating descriptive terms meaning 'possessing or provided with', resulting in a word that literally means 'having teeth like a saw'. this transparent compounding logic creates an instantly recognizable image of a jagged, notched outline.

Structure: saw (cutting tool) + tooth (projection) + ed (adjective suffix) saw (old english 'sagu', a cutting tool with a serrated edge); tooth (old english 'tōþ', a hard projection in the mouth, here used metaphorically for any pointed projection); ed (old english suffix forming adjectives from nouns, meaning 'having the quality of').
