'bleat' is the definition.
(synonyms)

'a sad hearted bachelor' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'bachelor' could be 'ba' (abbreviation for Bachelor of Arts degree) and 'ba' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'like' is the link.

Can you help me to learn more?
