Assertion in sign language
Assertion is a way of asserting that something will happen, is sure, is affirmative, is positive, assures, etc. Like negation, it's commonly used in sign language.
The characteristics of assertion are all or some of the following: head nod or nodding repeatedly; firm expression (brows burrowed, eyes squinted); and, tight or closed lips.
Note: it is a regular "worry" sign without assertion nor negation.
Translated: "worry" with an assertion.
Meaning examples: "definitely worry", "sure am worried"
Translated: "have" with assertion.
Meaning examples: "do have", "definitely exist", "it's indeed there!"
Translated: "have to" with assertion
Meaning examples: "must", "have to!" (as if with no choice).
Sometimes, assertion is used throughout a sentence.
