Suggestion pub venture's ending in ruin (8)

Ross

I believe the answer is:

innuendo

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

'suggestion' is the definition.
(thesaurus)

'pub venture's ending in ruin' is the wordplay.
I cannot really understand how this works, but
'pub' could be 'inn' (I've seen this before) and 'inn' is located in the answer.
'ending' could be 'end' (end is a kind of ending) and 'end' is found within the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for innuendo that I've seen before include "Suggestiveness" , "End union with insinuation" , "Rude suggestion" , "Implied smut" , "Insinuation - suggestion" .)

I've seen this clue in The Telegraph.
