Force king into shoddy establishment (5)
I believe the answer is:
drive
'force' is the definition.
(driving is a kind of forcing)
'king into shoddy establishment' is the wordplay.
I cannot really see how this works, but
'king' could be 'r' (abbreviation for rex, king in Latin) and 'r' is found in the answer.
'establishment' could be 'dive' (I have seen 'Low establishment ' mean 'dive' so perhaps 'establishment' could also mean 'dive') and 'dive' is located in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for drive that I've seen before include "High motivation, ambition" , "Strong motivation, ambition" , "Impel; house approach" , "Urge along" , "natural urge" .)
