Expand general mobilisation (7)

I believe the answer is:

enlarge

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

'expand' is the definition.
(I know that expand can be written as enlarge)

'general mobilisation' is the wordplay.
'general' anagrams to 'ENLARGE'.
But, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for enlarge that I've seen before include "Expand" , "Broaden, increase" , "swell?" , "Grow" , "Widen" .)

I've seen this clue in The Irish Times.
