Nadawca

Nadawca is a Polish noun meaning the sender or originator of a message, parcel, or signal. It is derived from the verb nadawać, “to send” or “to emit,” and is used for masculine singular; the feminine form is nadawczyni, and the plural forms are nadawcy (masculine personal) and nadawczynie (feminine).

In postal and parcel services, the nadawca is the person or entity that initiates the shipment. The term is commonly paired with odbiorca, the recipient, and a return address is referred to as the “adres nadawcy.”

In broadcasting and telecommunications, nadawca denotes the transmitter or broadcaster—the source of a radio or television signal, or of a digital message. The emphasis is on origin rather than destination.

In data processing and digital communication, nadawca appears as the sender field in messages, emails, or logs; it identifies who transmitted the data. Privacy and data-protection considerations apply to nadawca information, as with other personal data, requiring appropriate handling.

The word can also be used metaphorically to denote the initiator of ideas, actions, or information flows, not necessarily a physical person.
