While "agree" can be applied to both the act of agreeing with someone and the state of being in agreement (such as agreeing to a plan or being in agreement on a policy), "concur" is typically used to explicitly state one's agreement with another's opinion or decision.

Agree and concur are two words that are often used interchangeably in conversation, but they actually have slightly different meanings. Agree typically means to have the same opinion or belief as someone else, while concur means to agree with someone else's opinion or decision.

While "concur" often follows deliberation or evaluation, indicating a meeting of minds on a specific matter, "agree" encompasses a broader spectrum of alignment, including agreements on plans, opinions, preferences, and contracts.
