The term 'PARA' is a prefix for chute or legal, and it is four letters long. It is derived from the Greek word 'para, ' meaning 'beside, near, or beyond.' This prefix is commonly used in words such as parachute, paralegal, and parallel. It is also used to describe something that is related to, but not the same as, another thing. For example, a paramedic is someone who provides medical care in an emergency situation, but is not a doctor.
