Other forms: arrived; arriving; arrives
To arrive is to come to a destination. When you arrive in Paris, the first thing you should do is go and buy a croissant.
The word arrive generally means to come to a physical destination, like a place. Make sure you arrive home on time for dinner! But it can also be less literal. You can arrive at a conclusion or a decision after much thought. You can also use arrive to mean "achieve great success," though for whatever reason, this specific usage tends to be in the past tense. If you serve champagne and caviar at a party, your snobby aunt might comment, "My dear, you’ve arrived!” In this case, arrive means to come to a place of great wealth or success.
