Rather comprehensive book on mathematical vocabulary. There are many words sometimes barbaric appearance accompanied by etymological explanations and guidance on their use which helps to understand the choice of words, sometimes avoiding certain obstacles and sheds or the concepts behind the words. The words are sometimes very simple (such as "Rule") and sometimes complicated (like "rhumb" or "Grassmann"); they are used in college or high school, but not only because some of them are defined in college. A majority of the words are still simple and widely used in mathematics. Book profitable at any curious mind and every learner.
