Renown in association with yours truly (4)
I believe the answer is:
fame
'renown' is the definition.
(synonyms)
'association with yours truly' is the wordplay.
'association with' becomes 'fa' (I can't justify this - if you can you should give a lot more credence to this answer).
'yours truly' becomes 'me' (the person who set this crossword).
'fa'+'me'='FAME'
'in' is the link.
Can you help me to learn more?
(Other definitions for fame that I've seen before include "''... is the spur that the clear spirit doth raise (Lycidas, John Milton)" , "Repute" , "Favourable public reputation" , "Musical - stardom" , "Prominence" .)
