Demonstratives are words with a deictic function that single out a noun or pronoun and indicate that it stands out in a semantic context for one reason or another.In English we have two deictic articles, this and that. In Gaelic, demonstratives are not articles but particles that follow nouns. Three different particles are used: seo (here/this), sin (there/that), "siud" (yonder/that over there).
