To rest means to stop working or moving so your body and mind can relax and feel better. You can rest by sitting down, lying in bed, or taking a break from something tiring. Rest also means the part that is left after something is used or taken, like the rest of a cake after someone eats a slice. Whether you rest your head on a pillow or rest your legs after walking a lot, the word is about pausing and feeling calm or leaving something for later. Examples: • I need to rest after running around all day. • You should rest your feet on the stool to make them feel better. • Let’s eat the rest of the cake tomorrow. • He told her to rest on the couch and drink some water. • The rest of the team stayed to finish the project.
