Seafarer loves poor excuse (7)

I believe the answer is:

absolve

I'm a little stuck... Click here to teach me more about this clue!

'excuse' is the definition.
(I've seen this before)

'seafarer loves poor' is the wordplay.
'seafarer' becomes 'ab' (I am not sure about this - if you are sure you should believe this answer much more).
'poor' indicates anagramming the letters.
'loves' anagrammed gives 'solve'.
'ab'+'solve'='ABSOLVE'

Can you help me to learn more?

(Other definitions for absolve that I've seen before include "Acquit - free of blame" , "Lob vase (anag.)" , "Declare (someone) guilt-free" , "Grant pardon for" , "Free (a person) from guilt" .)
