Did you know?
A cadence is a rhythm, or a flow of words or music, in a sequence that is regular (or steady as it were). But lest we be mistaken, cadence also lends its meaning to the sounds of Mother Nature (such as birdsong) to be sure. Cadence comes from Middle English borrowed from Medieval Latin’s own cadentia, a lovely word that means “rhythm in verse.” (You may also recognize a cadence cousin, sweet cadenza, as a word that is familiar in the opera universe.) And from there our cadence traces just a little further backward to the Latin verb cadere “to sound rhythmically, to fall.” Praise the rising and the falling of the lilting in our language, whether singing songs or rhyming or opining on it all.
