Recalled Siamese couple in pronouncement (4)
I believe the answer is:
thai
'pronouncement' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for thai that I've seen before include "countryman" , "Morte d'16author" , "From old Siam?" , "A hit (anag)" , "Asian language" .)
