Notes:
The sign NATIONAL can also mean natural nature normal
NATIONAL natural nature normal vs OF COURSE
However sometimes skilled Deaf signers use the circle and drop version for: of
course. It is fairly easy to find video evidence.
See:
For an example of the circle and drop version of "of course" see the 7:38 mark
of: https://youtu.be/YcvpgZt8d0g?t=454
For another example of the circle and drop version of "of course" see the 13:58
mark of: https://youtu.be/nlZiGUd6ViM?t=837
For another example of the circle and drop version of "of course" see the 1:15
mark of https://youtu.be/6E_MckK5Ea4?t=74
For another example of the circle and down version of "of course" see the 6:16
mark of https://youtu.be/cW3ZeoM5PsE?t=375
So the difference between NATURAL and OF COURSE is not and always or never
situation.
OF COURSE Versions: 1. uninflected 2. inflected for emphasis (overlaps the
NATIONAL sign).
If taking an expressive test -- do "of course" this way: __ --------------------
...and do NATIONAL this way: __
