そんなに

まして use of そんなに is to express a strong degree or extent, often in questions or negative statements. It emphasizes that something is more or less than expected or usual. It is commonly used in casual to polite speech to ask whether something is to a surprising degree, or to deny that something is as much as one might think. Note that そんなに is typically followed by adjectives, verbs, or nouns in existential form (～がある・いる) when indicating quantity or extent. In negative sentences, そんなに + …ない is a very common pattern to say “not that much.” In positive statements, it can also reinforce a surprising level. }
