Renowned saw (5)
I believe the answer is:
noted
I believe this is a double definition.
'renowned' is the first definition.
(synonyms)
'saw' is the second definition.
(I've seen this before)
(Other definitions for noted that I've seen before include "Observed or took account of" , "Gaiter; oyster spawn" , "Recorded in writing" , "Wrote it down" , "remarked upon" .)
