Figure of speech
A figure of speech was a word or phrase or other form of expression used to convey meaning or heighten effects by comparing or identifying one thing with another that had a meaning familiar to someone else. Certain figures of speech may differ significantly from the literal meaning of the words involved; a way to express intricate and culturally-sensitive statements. Euphemisms covered a broad array of figures of speech; as did colorful metaphors, which might be used to express emotion. ()

The most common types of figures of speech were comparisons, which consisted primarily of metaphors and similes.

In 2364, Beata apologized for referring to men in their society as belonging to the women after William T. Riker told her men were not objects one could own. ()

In 2372, The Doctor explained his use of the word "our" to describe Samantha Wildman and Greskrendtregk's newborn baby Naomi Wildman, saying it was a figure of speech to technically ascribe part ownership of the child to himself, seeing as he helped deliver her. ()
