Etymology

Origin of adhere

First recorded in 1590–1600; from Medieval Latin adhērēre for Latin adhaerēre ( ad- ad- + haerēre “to stick, cling”), perhaps via Middle French adhérer

Explanation

If you don't want monkey droppings to adhere to the sole of your shoe, watch where you’re walking. Maybe if you'd adhere, or stick to, the zoo rules and stay on the walking path, you wouldn't have to worry about it. Adhere is from the 15th-century French verb meaning "to stick." Things that are sticky will adhere, or attach, to surfaces and stay there, whether you want them to or not; in other words, they're adhesive, an adjective that comes from the same Latin source as the French verb. When a person chooses to adhere to something, it is more of a choice to stick with it or agree to abide by rules or guidelines. You can also adhere by being loyal, as when you adhere to the high moral standards or behavior expected of some organization.
