intent on doing
intent on (doing something)
Determined to do something; set on doing something. I can't believe the invitations still aren't ready. It's like the printer is intent on ruining our wedding! She's intent on finishing her thesis this semester, but I just don't see how that's going to happen, with all the work she still needs to do.
intent on doing something
determined to do something. The children were intent on making a snowman. The prisoner was intent on escaping.
