Describes only one boarder in guesthouse at the western edge of town as rude (8)
I believe the answer is:
insolent
'rude' is the definition.
(I've seen this in another clue)
'describes only one boarder in guesthouse at the western edge of town' is the wordplay.
I cannot quite understand how this works, but
'only' could be 'sole' (synonyms) and 'sole' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for insolent that I've seen before include "Extremely fresh" , "Being discourteous and insulting" , "Impertinent" , "Impudent and disrespectful" , "Saucy" .)
