admittance

Admittance refers to the permission or official right to enter a place, attend an event, or access a restricted area. It is more than just the physical act of entering; it implies that an authority has authorized your presence. You'll often see it in notices and policies, as in "No admittance except on business" or "Admittance is by invitation only."

It can also refer to the price of entry: "free admittance" (no entry fee), "reduced admittance" (a discount), or "general admittance" (the standard ticket). In more formal writing, admittance sometimes overlaps with admission—acceptance into a school or organization, or the act of admitting someone to a hospital—but in modern everyday English, admission is usually the more common word for those ideas.

The word carries a strong sense of control—admittance is usually given or granted, not simply taken. It suggests that you have met specific criteria or possess the necessary credentials. Whether it's a concert hall, a secure workplace, or a private club, admittance signals the official granting of access.

In technical contexts (especially electrical engineering), admittance has a separate meaning: a measure of how easily current flows (the reciprocal of impedance).
