hint - A small or subtle piece of advice, suggestion, or information, often given to help someone understand something or solve a problem.

After a difficult 30 minutes in front of the group, my manager gave me a hint on how to improve my presentation.
badger - To repeatedly and annoyingly ask someone to do something.
Every time that Arnold asked Samantha to go out on a date, she would tell him firmly ‘No’. But each time he saw her, he would badger her again and again about wanting to go out, and again she said 'No!'
