A wart is a lump of abnormal skin growth that is caused by a virus. Depending on where they are, they can be painful. Some warts go away by themselves fairly quickly, others need to be removed by applying acid or by freezing them or cutting them off.
Something that looks like it has warts is described as warty. Toads look very warty, and so does the gourd in the picture.
Scientific name: phacochoerus africanus

You waste something when you have it, but you don't use it, or you use it for less important things. Someone might waste their money by buying lots of pairs of shoes and then complaining later they have no money for other things.
Waste is also leftovers, or something that is no longer needed and becomes trash. Anything you throw away is waste.
