Doldrums, where shade sought in part of boat (7)
I believe the answer is:
boredom
'doldrums' is the definition.
(thesaurus)
'shade sought in part of boat' is the wordplay.
I cannot really understand how this works, but
'shade' could be 'red' (red is a colour or shade) and 'red' is present in the answer.
'of' could be 'o' and 'o' is located in the answer.
This explanation may well be incorrect...
'where' acts as a link.
Can you help me to learn more?
(Other definitions for boredom that I've seen before include "no interest" , "Feeling" , "Monotony" , "weary idleness" , "Ennui in bedroom" .)
