Able seaman's beginning to get wasted (7)
I believe the answer is:
skilled
'able' is the definition.
(I've seen this before)
'seaman's beginning to get wasted' is the wordplay.
'seaman's beginning' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'to get' says to put letters next to each other.
'wasted' becomes 'killed' (I've seen this before).
's'+'killed'='SKILLED'
Can you help me to learn more?
(Other definitions for skilled that I've seen before include "Showing great aptitude" , "Trained, qualified" , "Highly trained" , "Expert, adroit" , "Proficient" .)
