$\sf\red{ \huge{Answer}}$

Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning.

Sign languages are expressed through manual articulations in combination with non-manual elements.

Sign languages are full-fledged natural languages with their own grammar and lexicon.
