Synonym discussion

Sense: noun/1

An inpatient is a patient who stays overnight in a hospital for treatment. The general term patient covers anyone receiving medical care — in a clinic, at a doctor's office, or in a hospital — without specifying whether they stay overnight. Outpatient is the direct opposite: a person who visits a hospital or clinic for an appointment, test, or minor procedure and leaves the same day. In hospital settings, resident is sometimes used informally to describe someone living temporarily in a facility, but it is not specific to medical patients. For example: 'The hospital discharged Vivek as an outpatient after his X-ray, but Nora was admitted as an inpatient for her surgery.'

Etymology

LatinEnglish

Formed in English in the late 1800s by combining the prefix in- ('within') with patient, which comes from Latin patiens ('suffering'). The word was created to distinguish hospital patients who stay overnight from those who visit for treatment only, who came to be called outpatients.
