E.g. for example (12)
I believe the answer is:
abbreviation
This might be a double definition.
'e g' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'example' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'for' acts as a link.
Can you help me to learn more?
(Other definitions for abbreviation that I've seen before include "plane, for example?" , "eg, may be one" , "EU, for example" , "BA, for example" , "RAF, for example" .)
