Old wobbly gut or weight to shed in maturity (7)
I believe the answer is:
outgrow
'to shed in maturity' is the definition.
I can't judge whether this defines the answer.
'old wobbly gut or weight' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'wobbly' is an anagram indicator (I've seen this in other clues).
'weight' becomes 'w' (short for weight).
'gut'+'or'='gutor'
'gutor' is an anagram of 'utgro'.
'o'+'utgro'+'w'='OUTGROW'
Can you help me to learn more?
(Other definitions for outgrow that I've seen before include "Develop faster or become taller than" , "Leave (something) behind as one matures" , "Get too big for" , "excel in development" , "Become too large or too mature for" .)
