Well known for having sporadically done time in (5)
I believe the answer is:
noted
'well known' is the definition.
(I've seen this before)
'having sporadically done time in' is the wordplay.
I cannot quite understand how this works, but
'time' could be 't' and 't' is present in the answer.
an anagram of 'done' is 'noed' which is located in the remaining letters.
No letters remain.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for noted that I've seen before include "Significant" , "Observed or took account of" , "Widely known and esteemed" , "Renowned" , "Like music" .)
