subatomic

I'm a little stuck... Click here to teach me more about this clue!

'move cubism to a very small scale' is the definition.
I can't tell whether this defines the answer.

'move cubism to a' is the wordplay.
'move' is an anagram indicator (I've seen 'moves' mean this).
'cubism'+'to'+'a'='cubismtoa'
'cubismtoa' anagrammed gives 'SUBATOMIC'.

Can you help me to learn more?

(Other definitions for subatomic that I've seen before include "Smaller than a basic particle of matter" , "Of smaller than elementary particles" , "Like 9 across" .)

I've seen this clue in The Daily Express.
