paradigm

The word paradigm is a very weird at least to me. When I looked the definition in the dictionary it was very confusing I read it about five times and still was confused. I called my mom to see if she could interpret it better. The definition that the dictionary said where two the first is, a set of forms all of which contain a particular element, esp. the set of all inflected forms based on a single stem or theme the second is, a display in fixed arrangement of such a set, as boy, boy's, boys, boys'. To me this was very confusing and is still is to be quite honest. After some long time of explaining what I think it means is when you have a word and you just put an apostrophe on it, it changes its meaning depending on where the apostrophe is placed on. But I’m not really sure about it I’m trying to find more information and examples on it.
