aroma

The word 'aroma' entered English in the late 13th century via Latin from the Greek word 'arōma', meaning 'spice' or 'sweet herb'. The Greek term itself is of uncertain origin, though it may be connected to a root meaning 'to plow' or 'to till', hinting at an ancient link to cultivated, fragrant plants. Over time, its meaning broadened from the source of the fragrance (the spice) to the fragrant quality itself. The modern sense of a distinctive, often pleasant smell, particularly from food or drink, retains this direct connection to its classical roots.

The word is a simplex loanword from Greek. It cannot be meaningfully segmented into smaller, independent morphemes using its current English spelling.
