Learning fine-grained distinctions between vocabulary items is a key challenge in learning a new language.For example, the noun "wall" has different lexical manifestations in Spanish -"pared" refers to an indoor wall while "muro" refers to an outside wall.However, this variety of lexical distinction may not be obvious to non-native learners unless the distinction is explained in such a way.In this work, we present a method for automatically identifying fine-grained lexical distinctions, and extracting concise descriptions explaining these distinctions in a human-and machine-readable format.We confirm the quality of these extracted descriptions in a language learning setup for two languages, Spanish and Greek, where we use them to teach non-native speakers when to translate a given ambiguous word into its different possible translations.Code and data are publicly released here.1
