Putter knack: fit club evenly behind (10)
I believe the answer is:
articulate
'putter' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
'knack fit club evenly behind' is the wordplay.
'knack' becomes 'art' (both can mean a skill or talent).
'evenly' means one should take alternating letters (the letters in even-numbered positions).
'behind' becomes 'late' (as in behind schedule).
'fit'+'club'='fitclub'
The alternating letters of 'fitclub' are 'icu'.
'art'+'icu'+'late'='ARTICULATE'
Can you help me to learn more?
(Other definitions for articulate that I've seen before include "well-spoken" , "Provide joint" , "Clear and fluent in speech" , "Express coherently" , "say" .)
