I'm a little stuck... Click here to teach me more about this clue!

'one saying too much' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'a bumbler? both oddly' is the wordplay.
'oddly' is an anagram indicator (letters in an odd order).
'a'+'bumbler'+'both'='abumblerboth'
'abumblerboth' anagrammed gives 'BLABBERMOUTH'.

Can you help me to learn more?
