Very much dislike endless swearing (4)
I believe the answer is:
oath
'very much dislike endless swearing' is the definition.
I know that 'swearing' relates to this answer.
'endless swearing' is the wordplay.
'endless' means to remove the last letter.
'swearing' becomes 'oaths' (I've seen this in another clue).
'oaths' with its last letter taken away is 'OATH'.
Can you help me to learn more?
(Other definitions for oath that I've seen before include "Vow, sworn word" , "It's taken in court" , "blasphemy" , "A word with a witness" , "Solemn promise to tell the truth or be loyal" .)
