radios

1. 1
   noun

   Plural of radio.

   Emergency crews carried portable radios into the disaster zone.

   Vintage radios from the 1940s sell for high prices at auctions.

   Note

   Only the countable meanings of radio can be counted: a receiver, a car's audio system, a transmitter. The technology itself and internet broadcasting stay uncountable, so radios always means devices. A career is made in radio, never in radios. The spelling adds a plain -s, not -es, and the same form also serves as the verb's present tense.

2. 2
   verb

   Third-person singular simple present of radio.

   The captain radios headquarters every hour to report the ship's position.

   A lifeguard radios the nearest station the moment a swimmer goes missing.

   Note

   The verb has two jobs, and this form carries both. Most often it means sending a message by two-way radio, with or without an object: she radios headquarters, or simply, the pilot radios. Used transitively, it can also mean directing someone to a place by telecommunications: dispatch radios a crew to the scene. The bare form radio serves I, you, we and they.
