Letter to order a horse? (3)
I believe the answer is:
gee
This clue could be a double definition.
'letter' is the first definition.
(G)
'order a horse?' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for gee that I've seen before include "Golly" , "Alphabet's seventh letter" , "Mild expression of surprise, may go before whiz" , "crumbs" , "provided by substitute for ginger?" .)
