The word infer is often used in thinking, reasoning, or daily talk. At its core, it means to form a conclusion from clues or facts, instead of being told directly. For example, if someone walks in soaking wet, you might infer that it is raining outside. This makes the word useful in study, debate, and even casual chat. Knowing the right Synonyms of Infer can help you explain ideas clearly and freshly.
