Dogmatic Opinion
I cannot find “Nikkari” in dictionaries in the sense of a smile.
“Nikkari” seems to me to be a smile that passes for “Nikkori.”
An image of smiling with the corners of the mouth lifted, the mouth open,
and the teeth visible.
An image that appeals to others to smile.
If it is a child, the impression is stronger and more satisfying than “Nikkori”.
“Beetle, I got it. !!!!!” Like that.
A look you never do when you are alone.
Proximate Expression
grin
