An air of devotion (5)
I believe the answer is:
psalm
This might be a double definition.
'an air' is the first definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'devotion' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'of' is the link.
Can you help me to learn more?
(Other definitions for psalm that I've seen before include "Old Testament lyrical poem or prayer" , "OT hymn" , "Lamps for a sacred song" , "Church song" , "Sacred song or hymn" .)
