Might one have guest for dinner? (8)

I believe the answer is:

cannibal

I'm a little stuck... Click here to teach me more about this clue!

'have guest for dinner?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'might one' is the wordplay.
I cannot quite understand how this works, but
'might' could be 'can' and 'can' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for cannibal that I've seen before include "Person eating human flesh" , "Eater of one's own kind" , "One eats human flesh" , "Person who has someone for dinner?" , "Animal that eats its own kind" .)
