More about olfaction
Olfaction contains two Latin roots: ol-, “to smell,” and fact-, “to make, do.” Ol- is a variation of od-, which is found in odor and deodorant. The change from d to l happened with several Latin words over time, which is also how the older word dingua, “tongue, speech,” evolved into Classical Latin lingua, as in bilingual, linguistics, and linguine—yes, the tongue-shaped pasta. Olfaction was first recorded in English in the 1840s.
