Question

One who speaks too much. One word answer

Answer 1

$\huge\bf\underline{Answer:}$

TALKATIVE

Answer 2

Answer:

A chatterbox is a person who speaks too much. But this is an informal word in English language and it is not a fit word to write down. So, a person who speaks too much can be formally called as talkative.

Other formal or informal words may include loquacious, voluble, gabby, chatty, gibbery, etc. It's up to you to choose the word that best fits the context.
