The condition or characteristic of having simple, single-cusped teeth without complex ridges or multiple points.
From haplodont + -y suffix (creating nouns for conditions or states). Converts the adjective describing teeth into a noun describing the overall dental condition.
Adding '-y' to create abstract nouns is an ancient English pattern, but in technical fields like paleontology, these '-y' words often appear only in academic papers and textbooks, never in conversation!
