The phrasal verb 'sign on' is predominantly used in informal contexts, though it can also appear in more formal settings, particularly in business or administrative language. Generally, it refers to the act of agreeing to or joining something by putting one's signature on a document, such as a contract or agreement, indicating acceptance or commitment. For example, one might 'sign on' for a job or service. It can be commonly found in contexts involving employment, where new employees 'sign on' to officially become part of an organization. Additionally, 'sign on' can be used within the technology field, referring to logging into a computer system or application, although this use is often labeled as 'sign in'. In British English, it has a particular usage related to registering for unemployment benefits. The flexibility of 'sign on' allows it to adapt to various scenarios involving formal agreement, entry, or commencement.
