How to use "cet", "ce" and "cette"?
I've been confused with the use of "ce", cette" and "cet".

Why is wrong using "CET chien est bruyant" or "CET verre est grand"?

I know that "ces" is the plural form, but I can't understand the use of "cette", "cet" and "ce"

I never know which one I should use :(

Answer

Cet ami.
Ce copain.
Cette amie / Cette copine.
(Masculine before a vowel, masculine before a consonant, feminine.)

Answer

I didn't look up the rule but french is my first language and right off the bat I can answer the following : Ce and Cet are used to present (demonstrative pronoun) masculine nouns, there is no fix rule to know which ones should be used, you must know it word by word (ce chien, cet engin, cet ami, cet homme, ce monstre) but generally ce if the masculine noun starts with a consonant and cet if it starts with a vowel. Cette is for feminine nouns.

Answer

Bonjour Cecilia,

Ce, cet, cette, ces = sont des adjetif démonstratif et ils s'accorde avec le nom.

Masculin      	                  Féminin  
Singulier     	           ce chat     	                          cette voiture  
Pluriel             		             ces arbres

« Ce » devient « cet » devant une voyelle ou un  « h »  muet :    cet acteur          cet homme
