Etymology: "Odorization" is a plain formation from "odor" with the suffix "-ization", the same pattern that gives words like "organization" and "standardization." The base "odor" reached English from Latin "odor", meaning smell or scent, while the "-ize" suffix comes from Greek through Latin and makes a verb meaning "to treat or cause to become something," with "-ation" turning that verb into a noun for the process. The word's elements are therefore older than English itself, but the combined noun is a modern technical coinage. The practice it names is much newer than its ancestors. Natural gas is odorless, so utilities add a strong-smelling compound, most famously mercaptan, so that a leak can be detected by smell before it becomes dangerous. The word describes that deliberate act of scenting a colorless, odorless substance, and it was built to name this specific safety measure rather than to describe smell in general.

Synonyms: scenting, fragrance
