It can also be a small bit of land which leads into a body of water. To spit is to propel something (usually saliva) from your mouth or to put something on a spit (i.e., impale). If you put something on a spit this morning, you spitted it, you can also be spitting a pig for dinner. If you ejected saliva from your mouth this morning, you spat; or you could say you spit (in the USA). A person could be spitting on the sidewalk right now. There are other definitions of the word spit, which include lighting something on fire, when it rains or snows lightly but strongly, or to make a spitting noise. Something can be the spitting image of something else if it looks just like it. A spat can also be a small fight or tiff between two people or groups.|
