Both "differentiate" and "distinguish" are verb transitive. They are of the same meaning. There are many words in dictionary and thesaurus which words are differentiating in their usage. If we use other words of the dictionary which are distinct. Do we have to use numerous words separately which are distinct?
If one does not want to use the words "differentiate" or "distinguish" repeatedly. If one wants to use dictionary, thesaurus meanings of the words, sometimes these are not appropriate and distinctly different. Will I have to go for higher study because there is no alternative? Can I use the word "between" after "differentiate" and "distinguish" if it is grammatical?
