When we go to earth, it means little (3)
I believe the answer is:
wee
'little' is the definition.
(similar in meaning)
'when we go to earth' is the wordplay.
I cannot quite understand how this works, but
'we' is found in the answer.
'earth' could be 'e' and 'e' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'it means' acts as a link.
Can you help me to learn more?
(Other definitions for wee that I've seen before include "Little (Scottish)" , "Mini in Glasgow?" , "Slash" , "Little or tiny in Scotland" , "It's small in Scotland" .)
