Lofty greeting to learners (4)
I believe the answer is:
hill
'lofty greeting to learners' is the definition.
I can't judge whether this defines the answer.
'greeting to learners' is the wordplay.
'greeting' becomes 'hi' (hi is a kind of greeting).
'to learners' becomes 'LL' (L-plates are seen on learner drivers' cars).
'hi'+'ll'='HILL'
Can you help me to learn more?
(Other definitions for hill that I've seen before include "pike" , "Miniature mountain" , "Small mountain" , "Box ---, Emma picnic site (J.Austen)" , "Raised area of land" .)
