We've learned now about the moon's lunar phases: new moon, waxing crescent, first quarter, waxing gibbous, full, waning gibbous and last quarter.
After last quarter, the moon continues to get darker on the right side.
Once it is almost totally dark and there is only a crescent of light on the left side, that is called waning crescent.
Remember that when the light crescent is on the right side, that is waxing crescent.
