Threw one into an outbuilding (5)
I believe the answer is:
shied
'threw' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'one into an outbuilding' is the wordplay.
'one' becomes 'i' (Roman numeral).
'into' is an insertion indicator.
'an outbuilding' becomes 'shed' (outbuilding in a garden).
'i' put into 'shed' is 'SHIED'.
Can you help me to learn more?
(Other definitions for shied that I've seen before include "horse did this?" , "Jumped nervously; threw" , "Thrown" , "Flung, tossed" , "started" .)
