Two letters read aloud in tent (6)
I believe the answer is:
teepee
'tent' is the definition.
(teepee is a kind of tent)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for teepee that I've seen before include "N. American native tent" , "Conical American Indian tent" , "Conical tent of American Indians" , "Tent used by American aborigines" , "Wigwam" .)
