Dissimilar means not alike or different from one another.
When people talk about something being dissimilar, they usually mean that it doesn't have any similarities with other things. For example, if someone says a painting and a photograph are dissimilar, they're saying that a picture done by hand (the painting) is very different from a digital image (the photograph). It's not just that they look different, but also that the way they were made, the materials used, and even the style of art are all unique. This word can be useful when comparing two or more things that don't have much in common.
Not similar; unalike; different.
