Shrill native Americans getting through school year (8)
I believe the answer is:
screechy
'shrill' is the definition.
(thesaurus)
'native americans getting through school year' is the wordplay.
'native americans getting' becomes 'cree' (I am not sure about this - if you are sure you should believe this answer much more).
'through' means one lot of letters goes inside another (inserted letters go through the word).
'school' becomes 'sch' (abbreviation).
'year' becomes 'y'.
'cree' going into 'sch' is 'screech'.
'screech'+'y'='SCREECHY'
Can you help me to learn more?
(Other definitions for screechy that I've seen before include "Harsh and shrill" , "Shrieky" , "Making harsh and piercing cries" , "Crying loudly" , "Loud and shrill" .)
