Impatient Is An Adjective

Word Origin And History
The history behind these words explains why they are unrelated.
Origin Of Impatient
Impatient comes from the Latin word impatiens, which means unable to endure or unable to bear something calmly.
Over time, English speakers began using it to describe someone who dislikes waiting or becomes frustrated easily.
Origin Of Inpatient
Inpatient is a modern medical term that became common during the twentieth century.
It combines in, meaning inside, with patient, referring to someone receiving medical care.
The word literally means a patient staying inside a hospital.
Although both words contain patient, they developed for different reasons and belong to different areas of English.

Writers and speakers in the United States, the United Kingdom, Canada, Australia, and New Zealand use both words with the same meanings.
