What does reinforce mean?
To reinforce is to make something stronger, more secure, or more firmly established. The word can refer to physical strengthening, as when a wall is reinforced with steel, or to the increased force of an idea, policy, expectation, or message. Reinforcing a rule does not merely announce it; it can make the rule more prominent, credible, or difficult to disregard. The word is common in education, organizations, construction, engineering, and public communication. Its figurative uses often carry the implication of support or confirmation, as when evidence reinforces an argument or a manager reinforces a policy. While it can suggest repetition, it more precisely conveys the effect of making an existing belief or structure stronger rather than simply saying something again.
