Pretexts come from being among local ibis (6)
I believe the answer is:
alibis
'pretexts' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'come from being among local ibis' is the wordplay.
'ALIBIS' is hidden within the letters.
But, I'm not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for alibis that I've seen before include "They're useful to have if accused of crimes" , "Pleas of being elsewhere at the time of a crime" , "Excuses" , "Defences of being elsewhere at the time of a crime" , "Proofs accused was elsewhere at time of crime" .)
