Ways to tell them apart:
Pre in premature means before, hinting that something occurs earlier than expected.
Immature starts with imm, which is part of immature, meaning something that is not fully grown or developed.
Premature often relates to timing, while immature relates to development or behavior.
Premature events happen earlier than the natural time, whereas immature is the opposite of mature, regardless of mind or age.
Remember the pre for time-related events and imm for growth and behavior related descriptions.
