1. To descend from the air and set down on top of someone or something. The wasp landed on my arm, so I had to stand perfectly still until it flew off again. His ball landed on Mrs. Thomson's rose bush, ruining dozens of the flowers.

2. To become the burden or responsibility of someone, especially very suddenly, unceremoniously, or without prior notice. It always lands on me to deal with the boss's stupid mistakes. Blame for their loss has to land on the team's coaching staff.
