Agree with a number of Romans and give way (6)
I believe the answer is:
accede
'agree with' is the definition.
(thesaurus)
'a number of romans and give way' is the wordplay.
'a number of romans' becomes 'ac' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'give way' becomes 'cede' (I've seen this in another clue).
'ac'+'cede'='ACCEDE'
Can you help me to learn more?
(Other definitions for accede that I've seen before include "Succeed to or allow" , "Agree (to) - come into office" , "Grant, agree to proposal" , "Assume" , "Comply" .)
