hear it again

: expressing or causing scornful ridicule

Example sentence:
She mocked her brother's temper tantrums with a derisive laugh, though she knew she ought to be kinder to him.

Etymology:
"Deridere" is the Latin verb meaning "to laugh at," and it comes from the prefix "de-" and the verb "ridere," meaning "to laugh." "Deridere" was borrowed into English as "deride," meaning "to ridicule," and "derisive" is an adjectival descendent of "deride." "Ridere" has another common English descendant: "ridiculous." "Ridiculous" comes from the Latin "ridiculus," meaning "laughable."
