Getting the ball, I have a knock up in the yard (5)
I believe the answer is:
patio
'yard' is the definition.
(I've seen this before)
'getting the ball i have a knock up' is the wordplay.
'getting' indicates putting letters inside.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'ball' becomes 'o' (letter resembling a ball).
'have' becomes 'ap' (I am not sure about this - if you are sure you should believe this answer much more).
'a knock up' says the letters should be written in reverse (I've seen 'knocking up' mean this).
'o'+'i'+'ap'='oiap'
'oiap' written backwards gives 'paio'.
't' inserted within 'paio' is 'PATIO'.
'in the' is the link.
Can you help me to learn more?
(Other definitions for patio that I've seen before include "Paved eating area adjoining house" , "Place to sit" , "inner court" , "Barbecue location?" , "Paved area next to house" .)
