The other day, I was watching the weather channel, and, saw a sign language presenter signing.
The specific sign language was known to me (as, most likely, was the one corresponding to the language spoken (although, there could be more than one sign language for any given language, of course (in which case I would have to guess))).
But, besides this, and although it was a bit hard for me to follow, one particular sign struck me, so much that I wanted to look it up in a dictionary.
The presenter held their left hand at chest level, flat, with the palm pointing up, with the fingers joined and pointing to the right, and, above it, a right hand was placed, with the fingers joined, in the shape of a "C", or, perhaps, that if a shell, with the four long fingers in front and the thumb at the back, fingers and thumb of the right hand touching the palm of the left hand, ... and almost making a tightening grasping movement, although only slightly.
What I want to know, is, with this information describing the sign, and knowledge of the language spoken, how could I look this sign up in a dictionary (and, what such dictionaries are available, for example, on Android systems)?
It seems to me, that entering the described information, would or could be a bit comolex, and a complex lookup system would be needed, (similar, perhaps, to looking up Chinese characters in a Chinese dictionary via radicals).
In my particular case, the language is one of the sign languages spoken in Italy (but, because signs are widely used even across different languages with different meaning, and I am looking for an example, even a dictionary pertaining to another language would do (and I could, very enthusiastically, use it to decipher signs in that language).
Thank you for your help.
