Simple programme about energy plant (5,4)
I believe the answer is:
apple tree
'plant' is the definition.
The answer is an example.
'simple programme about energy' is the wordplay.
'simple programme' becomes 'applet' (I have seen 'modest programme' mean 'applet' so perhaps 'programme' could also mean 'applet'. I am not sure about the 'simple' bit.).
'about' becomes 're' ('re' means regarding or about).
'energy' becomes 'e' (physics symbol as in E=mcp).
'applet'+'re'+'e'='APPLE-TREE'
Can you help me to learn more?
(Other definitions for apple tree that I've seen before include "fruit producer" , "Source of the growth that inspired Newton?" , "Plant bearing pippins" , "where Jonathan hangs out" , "source of fruit" .)
