* Infant: This is a general term used for a young monkey, similar to how we use it for human babies.
* Joven: This is used for young monkeys in Spanish.
* Baby: This is the most common and simple term used for a baby monkey.
* Young: This is a more scientific term, often used in research or academic contexts.
For specific species of monkeys, there may be more specific terms. For example, a baby chimpanzee might be called a "chimp", a baby gorilla a "young gorilla", and a baby orangutan a "baby orangutan".
Ultimately, the best way to refer to a baby monkey is to use a term that is appropriate for the specific species and context.
