Service deserves personal abbreviation (7)

I believe the answer is:

vespers

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

'service' is the definition.
(vespers is a church service)

'deserves personal abbreviation' is the wordplay.
'VESPERS' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for vespers that I've seen before include "An hour of worship" , "Evensong - RC service" , "Evening prayers" , "Evening service" .)

I've seen this clue in the Sydney Morning Herald.
