Splodge is a word commonly used to describe a big, uneven and often unsightly mark or stain. However, there are several synonyms that can be used to describe the same thing. Blot, splotch or smear are all words that can be used interchangeably with splodge, depending on the context. For example, a painting could have a splodge of paint, or a shirt could have a blot of ketchup on it. A splotch can also refer to a patch of discoloration, while smear is generally used to describe a mark made by rubbing or spreading something. These synonyms provide a varied vocabulary for those looking to describe marks in a more creative way.
