hike

A hike is a long walk.

A hike is an abrupt increase; usually referring to the increase in the cost of something.

Example: The tenants were not happy with the rent hike.

If you go hiking, you take a long walk for pleasure or exercise.

Example: Don't forget to bring the map when we go hiking tomorrow.

If the price of something hikes, it increases unfairly or suddenly.

Example: The landlord hiked the rent from a $2000 to $4000, hoping to chase the tenants away.
