Go away, not having time for Native American (4)
I believe the answer is:
hopi
'native american' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'go away not having time for' is the wordplay.
'go away' becomes 'hopit' (I've seen this before).
'not having' suggests deleting specific letters.
'time for' becomes 't' (I've seen this in other clues).
'hopit' with 't' removed is 'HOPI'.
Can you help me to learn more?
(Other definitions for hopi that I've seen before include "Pueblo tribe member" , "North American Indian people" , "Arizona inhabitant" , "Member of a Pueblo Indian people of northeastern Arizona" , "Language" .)
