Gave inside information to head on school sports day (6)
I believe the answer is:
tipped
'gave' is the definition.
(tipping is a kind of giving)
'information to head on school sports day' is the wordplay.
'information' becomes 'i' (common abbreviation for information).
'head' says to take the initial letters.
'on' means one lot of letters go next to another.
'school sports' becomes 'ppe' (I am not sure about this - if you are sure you should believe this answer much more).
'day' becomes 'd' (abbreviation for day).
The initial letter of 'to' is 't'.
'i' put after 't' is 'ti'.
'ti'+'ppe'+'d'='TIPPED'
'inside' is the link.
Can you help me to learn more?
(Other definitions for tipped that I've seen before include "Given a gratuity" , "Predicted to be a winner" , "Gave reward (to waiter)" , "Crowned" , "Gave gratuity to or touched" .)
