IPA: /ˈɛərtaɪm/
KK: /ˈɛrˌtaɪm/
The period when a radio or television program is being shown or heard.
The show will air during prime airtime on Friday nights.
Airtime is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "time" (from Old English "tima", meaning a period or duration). The word "airtime" refers to the time allocated for broadcasting in the air, particularly in radio or television.
Think of 'air' as the atmosphere where broadcasts happen and 'time' as the duration allocated for those broadcasts. This helps you remember that 'airtime' is the time spent broadcasting in the air.
