Streak about state with energy (4)
I believe the answer is:
lace
'streak' is the definition.
The answer and definition can be both to do with creating things as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
'about state with energy' is the wordplay.
'about' is a reversal indicator.
'state' becomes 'cal' (short for California).
'with' is a charade indicator (letters next to each other).
'energy' becomes 'e' (physics symbol as in E=mca).
'cal' written backwards gives 'lac'.
'lac'+'e'='LACE'
Can you help me to learn more?
(Other definitions for lace that I've seen before include "Spike - ornamental fabric" , "Shoestring: delicate ornamental fabric" , "Fabric made in openwork design" , "Tear" , "Fine open fabric" .)
