If you're looking for a positive way to describe someone as 'wordy' you can always use the word 'eloquent' which is also derived from 'loqui'. So there you go! I love that about it first off, that the Latin word was developed in two senses to make two words that mean basically the same thing, but each with their own positive or negative light. Super cool in my books. The dictionary definition is below!
