Adjective is a word that, when analyzing its etymological origin, we discover that it comes from the Latin term “adiectivus”. This can also determine that it is made up of three components: the prefix "ad-", which indicates an approximation; the verb "iacere", which can be translated as "launch", and finally the suffix "-tive", which is synonymous with "relationship".
The adjectives are words that determine or qualify a noun. It is a kind of word that expresses the properties attributed to the noun, highlighting or specifying them.
A demonstrative adjective is one that indicates a relationship of place, expressing the proximity of the person with whom or of whom one speaks. These adjectives always precede a noun; otherwise, we are dealing with another type of word (pronouns).
Likewise, we cannot ignore the knowledge that demonstrative adjectives always have the same gender and number as those of the nouns they accompany.
"That" , "this" , "that" , "that" and "those" are examples of demonstrative adjectives. There are some adjectives that are appropriate from the standpoint of grammar but are very archaic in everyday speech as "esotro" , "aqueste" or "aquesa" .
Specifically, we would have to establish that this is the complete list of demonstrative adjectives:
• Regarding the adverb category, there are the following: “here”, “here”, “there”, “there” and “there”.
• Those framed within the “masculine singular” section are these: “this”, “that” and “that”.
• On the other hand, typified as “singular feminine” we find “this”, “that” and “that”.
• "These", "those" and "those" are the plural masculine demonstrative adjectives.
• "These", "those" and "those" are, for their part, the feminine and plural type.
"That dog is a doberman" is an expression that includes the demonstrative adjective "that . " This adjective is determining the noun "dog" and assumes that the speaker is observing the "dog" in question so that the adjective "that" makes sense.
"Those girls are making a lot of noise and they won't let me rest" is another phrase where a demonstrative adjective ( "those" ) is used. The expression refers to a group of noisy girls according to the speaker's perspective.
On occasions, the demonstrative adjective can indicate both spatial and temporal proximity: “Yesterday I bought this record” uses the adjective “this” to refer to a spatial proximity (it is easy to imagine the speaker pointing to the record in question or holding it by hand), while "This winter we will go skiing" includes the same adjective in a temporal reference (the winter that is lived at the moment or that is to come).
That is to say, we could use the demonstrative adjectives already exposed to establish the type of proximity and closeness that they establish in terms of a subject or a specific object. In this sense, the following characteristics have been specified in this regard:
• Those that indicate the greatest proximity are “this”, “this”, “these” and “these”.
• On the other hand, those who come to show an average distance are “that”, “that”, “those” and “those”.
• Finally, those used to indicate a greater distance are “that”, “that”, “those” and “those”.
