Yes. We can find the word dictionary in a dictionary. When I referred to the Oxford Dictionary, I came across the following meaning.
Dictionary: A book or electronic resource that lists the words of a language (typically in alphabetical order) and gives their meaning, or gives the equivalent words in a different language, often also providing information about pronunciation, origin, and usage.
