Grand lover somehow made to show humility (6)
I believe the answer is:
grovel
'to show humility' is the definition.
'grand lover somehow' is the wordplay.
'grand' becomes 'g' (G is short for grand as in a thousand).
'somehow' is an anagram indicator.
'lover' is an anagram of 'rovel'.
'g'+'rovel'='GROVEL'
'made' is the link.
(Other definitions for grovel that I've seen before include "Cringe in abject manner" , "Crawl, fawn" , "Behave obsequiously, crawl" , "Behave obsequiously, humble oneself" , "Crawl abjectly" .)
