Etymology: "Aphyllous" is a 19th-century scientific coinage, built in New Latin from Ancient Greek "áphullos", meaning "leafless". The Greek word is itself a compound of the privative prefix "a-", meaning "without", and "phúllon", "leaf". So the word is a precise, deliberately constructed label rather than something that drifted into botany from everyday speech. Botanists needed a single term for plants and plant parts that lack the leaves typical of their group, and reaching back to Greek for the building blocks gave them one. The core of the word is the same as in "phyllo" pastry and "chlorophyll", both of which take the Greek "phúllon" as their root. Anyone who knows those words already has most of the vocabulary needed to decode "aphyllous" on sight.
