demonstrative adjective การใช้

Deictic adverbs are often used in a noun phrase as demonstrative adjectives.
The definite article and its various forms could serve both as a definite article ( " the " ) and a demonstrative adjective ( " that " ).
Gregory of Tours writes, " Erat autem . . . beatissimus Anianus in supradicta civitate episcopus " ( " Blessed Anianus was bishop in that city . " ) The original Latin demonstrative adjectives were no longer felt to be strong or specific enough.
By contrast, when a sentence is in spoken form and the verb involved is one of assertion, the use of " that " makes clear that the present speaker is making an indirect rather than a direct quotation, such that he is not imputing particular words to the person he describes as having made an assertion; the demonstrative adjective " that " also does not fit such an example.
