Habitually late is a term used to describe someone who is consistently late for appointments or events. UNPUNCTUAL (10 letters) and TARDY (5 letters) are two words that can be used to describe this behavior. Both words imply that the person is not punctual or prompt in their actions. TARDY is often used to refer to someone who is late for school or work, while UNPUNCTUAL is more general and can be used to describe any situation where someone is late.
