The Yankee ones? (4)
I believe the answer is:
they
'ones?' is the definition.
Both the definition and answer are plural nouns.
Maybe there's a link between them I don't understand?
'the yankee' is the wordplay.
'yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'the'+'y'='THEY'
Can you help me to learn more?
(Other definitions for they that I've seen before include "Pronoun for more than one" , "Third person plural" , "People in general" , "Pronoun for people" , "People generally" .)
