The phrase "what is" is a common interrogative beginning used to ask for definitions, explanations, or descriptions of a concept, object, or phenomenon. It essentially seeks to clarify the nature or identity of something. For example, "what is love?" asks for an understanding or definition of the concept of love. If the question is about a specific topic or term, specifying that would help provide a precise explanation or definition. For instance, if asking "What is love?" it could refer to the emotional feeling, or a famous song by Haddaway released in 1993, among other meanings.
Please specify the subject or context if a particular explanation or definition is needed.
