Meaning, Tone & Context of ‘Block’

The word block has three main senses. As a verb, it means to stop or get in the way of something, like “The fallen tree blocked the road.” As a noun, it can mean a solid piece of material, like a block of wood or cheese. It can also mean a city block, the area between streets in a town.
