Suggestible bachelor is drenched in beer by alpha males (8)
I believe the answer is:
'suggestible' is the definition.
'beer by alpha males' is the wordplay.
'beer' becomes 'able' (I can't explain this - if you can you should give a lot more credence to this answer).
'by' is a charade indicator (letters next to each other).
'alpha' becomes 'a' (phonetic alphabet: alpha, bravo, charlie etc.).
'males' becomes 'men' (man is a kind of male).
'able' after 'amen' is 'AMENABLE'.
'bachelor is drenched in' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for amenable that I've seen before include "Open to suggestions" , "Ready to accept" , "Willing to yield or be influenced" , "Accommodating; flexible" , "Open and responsive to suggestion" .)
