Free from guilt sailor loves partying (7)
I believe the answer is:
absolve
'free from guilt' is the definition.
'absolve' can be an answer for 'free' (to absolve is to free or spare from blame). I'm unsure of the 'from guilt' bit.
'sailor loves partying' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'partying' indicates anagramming the letters (I've seen 'parties' mean this (the letters move or party around)).
'loves' with letters rearranged gives 'solve'.
'ab'+'solve'='ABSOLVE'
Can you help me to learn more?
(Other definitions for absolve that I've seen before include "Exculpate" , "Declare (someone) blameless" , "free of error" , "Discharge" , "Free (a person) from guilt" .)
