Headlong is an adverb that means to do something recklessly or without thinking about the consequences. It can be used to describe a physical action, such as jumping headlong into a swimming pool without checking how deep it is, or a figurative action, such as rushing headlong into a business decision without considering all the options. It is important to be careful when using this word, as it implies a sense of danger and lack of caution.
