Goes off using oars without power (6)
I believe the answer is:
addles
'goes off' is the definition.
The answer and definition can be both related to change as well as being verbs in their -s form.
Maybe they are linked in a way I don't understand?
'oars without power' is the wordplay.
'oars' becomes 'paddles' (paddle is a kind of oar).
'without' is a deletion indicator.
'power' becomes 'p' (symbol in physics).
'paddles' with 'p' removed is 'ADDLES'.
'using' acts as a link.
Can you help me to learn more?
(Other definitions for addles that I've seen before include "Confuses in saddle" , "Muddles, confuses" , "Confuses or goes bad" , "Confuses like bad egg" , "Makes rotten - makes muddled" .)
