A Logical Approach to Modal Verbs 1 Can and Could

Abstract The article aims at a logical approach to discussing can, could, and be able to, organized around core meanings such as possibility, ability, and permission. We argue that the concept of “remoteness” proposed by Lewis in 1986 may simplify enough the explanation regarding the relationship between can and could, and their presentation relies on authoritative sources published for international (English), Hungarian, and Romanian students. The conclusion discusses both the importance and relativity of a number of occurrences (depending on different text types), trying to offer a possible teaching option for modals stemming from practice. The article is connected to the international conference in Miercurea Ciuc, entitled Idegen - Străinul - Stranger, focusing on English as a foreign language through the eyes of non-native speakers.
