Not up on contranyms? Those are single words that have not just two meanings, but two meanings that are the opposite of each other. Like if "white" meant both "white" and "black" depending on how you referred to it.
Here's a few more:
Bound — Going somewhere, or prevented from going anywhere
Cleave — To stick together, or to cut apart
Continue — To keep doing something, or to stop doing something
Dollop — A lot, or not a lot
Liege — The person at the top in charge, or the person that the person at the top in charge is in charge of
Overlook — To pay attention to something, or to ignore something
Scan — To read closely, or to read quickly
Splice — To join together, or to split apart
At some point in history, someone probably railed against people saying "My alarm clock went off" because "off" shouldn't be allowed to mean "activated". Yet humanity somehow survived.
