Deliveries perhaps limited one day (5)
I believe the answer is:
overs
'deliveries' is the definition.
(over is a type of cricket delivery)
'perhaps limited one day' is the wordplay.
'perhaps' becomes 'ove' (I can't explain this - if you can you should believe this answer much more).
'limited' says to take the centre (the limits of the word are removed).
'one day' becomes 'thursday'.
The central letters of 'thursday' are 'rs'.
'ove'+'rs'='OVERS'
Can you help me to learn more?
(Other definitions for overs that I've seen before include "Maidens perhaps" , "Lots of deliveries" , "Series of balls in cricket" , "Periods of play" , "Rounds of six bowls in cricket" .)
