Comment, observation (6)
I believe the answer is:
remark
I believe this is a double definition.
'comment' is the first definition.
(a remark is a spoken comment)
'observation' is the second definition.
(I know that remark is a type of observation)
(Other definitions for remark that I've seen before include "Observation - notice" , "(E.g. Virgil's) pastoral poems" , "Notice or comment on" , "Written or spoken comment" , "what someone says?" .)
