Calm when it was called for (9)
I believe the answer is:
collected
'called for' is the definition.
('collect' can be a synonym of 'call for')
'calm when it' is the wordplay.
I cannot quite see how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is found in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'was' is the link.
Can you help me to learn more?
(Other definitions for collected that I've seen before include "Also cool and calm?" , "Brought together" , "composed" , "Gathered" , "Came together" .)
