"Similar" means resembling or having a likeness to something or someone. It suggests that there are shared characteristics between two or more objects or concepts. For example, if two cars have the same color, model, and specifications, we can say they are similar.
"Same" means exactly alike or not different. It indicates that there is no variation or distinction between two or more objects or ideas. For instance, if two people have the exact same height, weight, and eye color, we can say they are the same.
In summary, "similar" implies some shared qualities, while "same" denotes complete uniformity. Both words serve as antonyms of "different," providing alternatives to express similarity or sameness in various contexts.
