Here are some examples of how it is used:
* Je vois un chat. (I see a cat.)
* Tu vois la mer ? (Do you see the sea?)
* Ils ont vu un film hier. (They saw a movie yesterday.)
It is important to note that the word voir is also used in a number of idiomatic expressions, such as:
* voir le jour (to be born)
* voir rouge (to see red, to become angry)
* voir clair (to see clearly, to understand)
These expressions have a different meaning than the literal meaning of voir and should be understood in context.
