Strong enough to make the top ten (6)
I believe the answer is:
potent
'strong' is the definition.
(I know that strong can be written as potent)
'make the top ten' is the wordplay.
'make' indicates an anagram.
'top'+'ten'='topten'
'topten' with letters rearranged gives 'POTENT'.
'enough to' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for potent that I've seen before include "Forceful" , "Intoxicating" , "Top Ten (anag.)" , "Concentrated or strong, like liquor" , "Mighty" .)
