Plant for example, storing container in passageway (9)
I believe the answer is:
eglantine
'plant for' is the definition.
'eglantine' can be an answer for 'plant' (I've seen this before). I am not certain of the 'for' bit.
'example storing container in passageway' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'storing' indicates putting letters inside.
'container' becomes 'tin' (tin is a kind of container).
'in passageway' becomes 'lane' (I can't explain this - if you can you should believe this answer much more).
'tin' placed within 'lane' is 'lantine'.
'eg'+'lantine'='EGLANTINE'
Can you help me to learn more?
(Other definitions for eglantine that I've seen before include "Rose, growing wild" , "Inelegant (anag) - plant" , "Inelegant (anag.); wild rose" , "Inelegant sort of sweet-brier" , "Strangely inelegant scented plant" .)
