Lure a number to slip on the ice (6)
I believe the answer is:
entice
'lure' is the definition.
(lure can mean to entice or attract)
'a number to slip on the ice' is the wordplay.
'a number' becomes 'en' (I can't justify this - if you can you should give a lot more credence to this answer).
'to slip' is an anagram indicator.
'on' is a charade indicator (letters next to each other).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
't' put after 'ice' is 'icet'.
'icet' with letters rearranged gives 'tice'.
'en'+'tice'='ENTICE'
Can you help me to learn more?
(Other definitions for entice that I've seen before include "act like clickbait" , "alluring" , "to offer temptation" , "Attract with offers" , "Tempt with promises of reward" .)
