👉 Tautonymy, in linguistics, is a type of synonym that involves two words being identical except for a change in one or both of their meanings. For example, "cat" and "dog" are tautonyms because they mean the same thing but have different meanings based on context. In other words, a word can be tautonymic if it is used more than once with the same meaning without changing its literal meaning. This type of synonym ensures that the language remains consistent
