When released, Flintstone got out of the way (5)
I believe the answer is:
freed
'when released' is the definition.
'freed' can be an answer for 'released' (I've seen this before). I'm not certain of the 'when' bit.
'flintstone got out of the way' is the wordplay.
I cannot really see how this works, but
'out' could be 'free' (I've seen this before) and 'free' is found within the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for freed that I've seen before include "Untied" , "Defer being liberated" , "Emancipated, let loose" , "Released" .)
