Did you know?
The adjective "lachrymose" comes from Latin "lacrimosus" (from the noun "lacrima," meaning "tear"). "Lachrymose" didn't appear in English until around 1727, but another closely related adjective can be traced back to the late 16th century. This earlier cousin, "lachrymal" (sometimes spelled "lacrimal," particularly in its scientific applications), has a scientific flavor and is defined as "of, relating to, or being glands that produce tears" or "of, relating to, or marked by tears." In contrast, "lachrymose" typically applies to someone who is moved to tears because of strong emotions or something that stimulates such feelings.
