Informant followed the plane sent out for fodder (8,5)
I believe the answer is:
elephant grass
'for fodder' is the definition.
The definition suggests a singular noun which matches the answer.
'informant followed the plane sent' is the wordplay.
'informant' becomes 'grass' (term for an informant or traitor).
'followed' means one lot of letters go next to another (some letters go after others).
'sent' indicates anagramming the letters (send can mean to excite or stimulate).
'the'+'plane'='theplane'
'theplane' anagrammed gives 'elephant'.
'grass' after 'elephant' is 'ELEPHANT GRASS'.
'out' acts as a link.
Can you help me to learn more?
(Other definitions for elephant grass that I've seen before include "source of paper" , "plain diet" , "tall plant" , "crop in Africa" .)
