A derelict pub, exhort to go into (6)
I believe the answer is:
beggar
'a derelict' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for beggar that I've seen before include "Pauper who lives by soliciting" , "vagrant" , "Pauper or supplicant" , "Mendicant or scrounger" , "bum" .)
