Thunnini? Some Bantu natives? (4)
I believe the answer is:
tuna
'thunnini?' is the definition.
I can't judge whether this definition defines the answer.
'some bantu natives?' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'TUNA' is hidden in the letters of 'bantu natives'.
Can you help me to learn more?
(Other definitions for tuna that I've seen before include "Bluefin, e.g." , "Popular food fish" , "Large fish found in a nut" , "Large salt water fish" , "Species of fish" .)
