And, as the tide's about to turn, clear the way for (5,5)
I believe the answer is:
stand aside
'turn clear the way for' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'and as the tide's about' is the wordplay.
'about' indicates an anagram.
'and'+'as'+'tides'='andastides'
'andastides' is an anagram of 'STAND ASIDE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for stand aside that I've seen before include "look on indifferently" , "Allow another to take charge - let me through!" , "Take no action to prevent something happening" .)
