Definition: that (determiner)
This signed determiner "that" can be a general locative or a locative-specific agreement in a sentence.
In English, there are two determiners: "this" and "that" depending on the referents in a sentence. But, the determiner in ASL is locative specific to a referent.
The gloss for this sign is usually noted as "THAT-ONE". Literally, it's THAT-IX. A link to the post explaining this usage and complex explanation will be added shortly.
