famous OR infamous?
These adjectives have rather different meanings, and different pronunciations. In simple terms, the difference is:
famous = Well-known
infamous = Well-known for something bad
If somebody is famous, then many people know about that person. Here are some famous people. You probably know all or most of them:
Notice that famous people can be good or bad. "Famous" does not "judge" people. It is just a statement that somebody is well-known.
Famous is objective (a matter of fact). Infamous is subjective (it tells you about the speaker's opinion).
If somebody is infamous, then many people know about that person because he did something bad. He has a "bad reputation".
Look at these example sentences:

In both words the stress is on the first syllable, which means that they sound very different.
