Does it make the noun smaller or bigger when you add ito to end of a noun?

Adding "-ito" to the end of a noun in Spanish typically makes it smaller. This suffix indicates diminutiveness, which means it makes the noun refer to something smaller or more delicate than the original noun.

Here are some examples:

* libro (book) -> librito (little book)

* mesa (table) -> mesita (small table)

* gato (cat) -> gatito (kitten)

* flor (flower) -> florita (little flower)

However, it's important to note that "-ito" can also be used for other purposes, such as expressing affection or endearment. In these cases, it doesn't necessarily imply a change in size.

For example:

* Mamá (mom) -> Mamita (Mommy)

* Amigo (friend) -> Amiguito (little friend)

In these examples, "-ito" adds a sense of warmth and closeness, but doesn't necessarily imply a smaller size.
