-Characterized by excessive talk; wordy.
From: 1660s, back-formation from loquacity or else formed from stem of Latin loquax (genitive loquacis) "talkative," from loqui "to speak" (see locution) + -ous.
Used in a sentence:
"There are very few things in life that annoy me more than a person who is equal parts ignorant and loquacious!”
If you've ever been described as talking too much and using grandiloquent words - wear this witty shirt with pride!
