admitted

The word “admitted” means allowed in or accepted, especially into a place, group, or profession. In plain terms, officially let in or accepted somewhere.

“Admitted” is pronounced uhd-MIH-tihd (/ədˈmɪtɪd/ in IPA).

Here is “admitted” used in a sentence: “She was admitted to the bar after passing her final exams.”

“Admitted” is an adjective.

“Admitted” is a fairly common word in modern English.

Both involve being allowed in, but "accepted" stresses approval, being formally offered a place, as in accepted to a university. "Admitted" stresses actual entry, being let in through the door or onto the register. You may be accepted by an institution and later admitted when you physically join.

Being admitted to hospital means you are formally taken in as an inpatient to stay for treatment, rather than being seen and sent home. Staff register your details, assign a bed, and take over your care. It contrasts with an outpatient visit, where you leave the same day.

In the sense of being allowed in, the opposite is excluded, refused, turned away, or barred. For hospitals or institutions, "discharged" is the natural counterpart, meaning released after having been admitted. The right opposite depends on whether you mean never let in, or let out again.
