Demonstrative Adjectives in French

In Enlgish, demonstrative adjectives are this, that, these and those.

In French, we don't usually make the distinction between something that is close and something that is far.

However, if you want to emphasize the location of something in relation to another thing,
or if you are answering the question (this chair or that chair?) (, we add "-ci" (this) or "-là" (that) after the noun.

Q: Do you want this chair or that chair?
A: I want that chair.
A: I want this chair.

ci - near
là - far

Q.: Tu veux cette chaise-ci ou cette chaise-là?
A: Je veux cette chaise-là.
A: Je veux cette chaise-ci.

In French, demonstrative adjectives are ce, cette and ces.

Examples:
This or that - ce (masc sing): this book - ce livre, that book - ce livre
This or that - cette (fem sing): this chair - cette chaise, that chair - cette chaise

Ce - Masuculine
Cette - Feminine.

These or those - ces (plur):
In plural it does not change with gender.

these books - ces livres,
those books - ces livres,

these chairs - ces chaises,
those chairs - ces chaises
