Impatient or Inpatient: Which Is Correct?

Updated 2026-10-03 · Which One Is Correct editorial team

Quick answer: Both impatient and inpatient are correct English words, but they mean completely different things. Use impatient to describe someone who lacks patience. Use inpatient to refer to a hospital patient who stays overnight. Knowing the distinction prevents awkward errors in writing.

The Short Answer

Both impatient and inpatient are correct, but they serve entirely different purposes in English. You should never use one as a substitute for the other because their meanings do not overlap in any standard context.

People confuse these words because they sound nearly identical and share the same suffix. The prefix 'im' suggests a negative quality, while 'in' often indicates location. This small spelling difference changes the definition from an emotion to a medical status.
