The man ran into the store room (7)
I believe the answer is:
granary
'store room' is the definition.
'granary' can be an answer for 'store' (I've seen this before). I am not sure about the 'room' bit.
'the man ran into' is the wordplay.
'the man' becomes 'gary' ().
'into' means one lot of letters goes inside another.
'gary' going around 'ran' is 'GRANARY'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for granary that I've seen before include "Harvest store" , "Store for, eg, corn" , "Storehouse for wheat or corn, say" , "Agricultural storehouse" , "(Of bread) containing whole grains of wheat" .)
