Blowing hot and cold for hundred thousand found in queue (6)
I believe the answer is:
fickle
'blowing hot and cold' is the definition.
I can't tell whether this defines the answer.
'hundred thousand found in queue' is the wordplay.
'hundred' becomes 'c' (Roman numeral).
'thousand' becomes 'K' (synonyms).
'found in' is an insertion indicator.
'queue' becomes 'file' (I've seen this in another clue).
'c'+'k'='ck'
'ck' placed inside 'file' is 'FICKLE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for fickle that I've seen before include "Subject to changes of mind" , "Inconstant in affections" , "Changeable, capricious" , "Unreliable" , "Having changing loyalties" .)
