Keep

Keep means to hold something, to continue doing something, or to have something and not let it go. For example, he keep his keys in his pocket (he holds them there), keep walking (don’t stop), or she decided to keep the gift because she liked it a lot (she did not give it away). It can also mean to take care of something, like they keep a pet dog. As a noun (rare), it can mean the central strong part of a castle, like the castle keep was the safest place during an attack. But most people only use “keep” as a verb in daily life.
