I see a struggle right to the end, though less arduous (6)
I believe the answer is:
easier
'less arduous' is the definition.
(I've seen this in another clue)
'i see a struggle right' is the wordplay.
'struggle' indicates anagramming the letters (letters move around or struggle).
'right' becomes 'r' (abbreviation).
'i'+'see'+'a'='iseea'
'iseea' is an anagram of 'easie'.
'easie'+'r'='EASIER'
'to the end though' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for easier that I've seen before include "More effortless" , "Requiring less effort" , "more like a piece of cake" , "Less taxing" , "More facile" .)
