Pitched one in an outhouse (5)
I believe the answer is:
shied
'pitched' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Perhaps you can see a link between them that I don't see?
'one in an outhouse' is the wordplay.
'one' becomes 'i' (Roman numeral).
'in' means one lot of letters goes inside another.
'an outhouse' becomes 'shed' (a shed is an outside building).
'i' placed into 'shed' is 'SHIED'.
Can you help me to learn more?
(Other definitions for shied that I've seen before include "started" , "Jumped nervously; threw" , "Flung, tossed" , "Thrown" , "Cast" .)
