threadbare

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

'not having a nap' is the definition.
I can't tell whether this definition defines the answer.

'trio outside commercial pub' is the wordplay.
'trio' becomes 'three' (synonyms).
'outside' indicates putting letters inside (some letters go outside others).
'commercial' becomes 'ad' (abbreviation for advertisement).
'pub' becomes 'bar' (both are drinking establishments).
'ad'+'bar'='adbar'
'three' enclosing 'adbar' is 'THREADBARE'.

Can you help me to learn more?

(Other definitions for threadbare that I've seen before include "Shabby" , "Ragged" , "cliche-ridden" , "deprived of nap" , "Frayed" .)
