In storm secure a support (8)
I believe the answer is:
baluster
'support' is the definition.
(I know that baluster is a type of support)
'in storm secure a' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
The remaining letters 'bluster' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for baluster that I've seen before include "Pillar supporting a rail, may be rustable" , "Type of decorative support for a rail" , "Rail hold-up" , "Set of posts supporting a rail" , "One of a number of closely spaced supports for a railing" .)
