It turns up on the tenth (5)
I believe the answer is:
tithe
'tenth' is the definition.
(I've seen this before)
'it turns up on the' is the wordplay.
'turns up' says the letters should be written backwards.
'on' means one lot of letters go next to another.
'it' back-to-front is 'ti'.
'ti'+'the'='TITHE'
(Other definitions for tithe that I've seen before include "Tenth part once paid as tax" , "donation to church" , "Church payment" , "One-tenth of income paid to church" , "Levy by church, e.g." .)
