 Priority. In 2021, the Rakianus Peninsula in Iceland experienced some volcanic activity after a quiet period of about 800 years. Earlier this year, a volcanic eruption sent hot lava into a nearby town where people had left their homes. Iceland's president said their return date is unknown, and the main priority is protecting human lives. Priority is the quality or state of coming before another in time or importance. Priorities are things that a person cares most about and considers most important.
