Distance over which there's a charge for finishing last? (4)
I believe the answer is:
feet
'distance over' is the definition.
'feet' can be an answer for 'distance'. I am not sure about the 'over' bit.
'there's a charge for finishing last?' is the wordplay.
'there's a charge' becomes 'fee' (fee is a kind of charge).
'for' means one lot of letters go next to another.
'finishing' says to take the final letters (the letter which finishes the word).
The last letter of 'last' is 't'.
'fee'+'t'='FEET'
'which' acts as a link.
Can you help me to learn more?
(Other definitions for feet that I've seen before include "On which we stand" , "Metrical units" , "Measures - body parts" , "Unit used to measure" , "Paws" .)
