It's enumerated poorly? (13)
I believe the answer is:
underestimate
'it's enumerated poorly?' is the definition.
I can't judge whether this definition defines the answer.
'it's enumerated poorly?' is the wordplay.
'poorly?' is an anagram indicator (a poor spelling).
'its'+'enumerated'='itsenumerated'
'itsenumerated' anagrammed gives 'UNDERESTIMATE'.
Can you help me to learn more?
(Other definitions for underestimate that I've seen before include "Regard (someone) as less capable than is the case" , "Evaluation that is too low" , "Low guess" , "Sell short" , "inaccurate" .)
