What does prefix "-im" mean? Could you give me other examples as well?

The prefix "im-" is used with words beginning with b, p, or m to form the opposite meaning of the word. Some other examples include "impolite," "immature," and "impossible." It can also be used to indicate direction into, in, or within something, such as "import," "imbue," "immigrate," and "implant." Ex: It's impolite to interrupt. => not polite Ex: It's impossible to live on the moon. => not possible Ex: I'm getting some dental implants next week.
