Bill fit to be split by men as dear (8)
I believe the answer is:
adorable
'dear' is the definition.
(thesaurus)
'bill fit to be split by men' is the wordplay.
'bill' becomes 'ad' (advertisement stuck on wall).
'fit' becomes 'able' (similar in meaning).
'to be split by' indicates putting letters inside (some letters split a word into two).
'men' becomes 'OR' (Other Ranks: non-commissioned soldiers).
'ad'+'able'='adable'
'adable' placed around 'or' is 'ADORABLE'.
'as' is the link.
(Other definitions for adorable that I've seen before include "Attractive - captivating" , "Worthy of worship" , "Loveable" , "Very pleasing" , "Lovely and attractive" .)
