Encourage around circuit (4)

Ross

I believe the answer is:

clap

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

'encourage' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?

'around circuit' is the wordplay.
'around' becomes 'c' (abbreviation for 'circa').
'circuit' becomes 'lap' (synonyms).
'c'+'lap'='CLAP'

Can you help me to learn more?

(Other definitions for clap that I've seen before include "Sudden loud noise (of thunder?)" , "Express approbation with the hands" , "Make sound of applause" , "Audibly show approval" , "express approval" .)
