A yawl's ever so different (6)
I believe the answer is:
always
'a yawl's ever so different' is the definition.
I can't judge whether this defines the answer.
'yawl's ever so different' is the wordplay.
I cannot quite see how this works, but
an anagram of 'yawl' is 'lway' which is located in the answer.
'so' could be 'as' (eg 'not as tall as me' means 'not so tall as me') and 'as' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for always that I've seen before include "Irving Berlin's enduring song" , "For good" , "Evermore" , "Forever, without interruption" , "Constantly" .)
