telefónico
/teleˈfoniko/ · B1 · adj
pertaining to telephones
☎️ tele (far) + fono (voice) + -ico = of the far-off voice
From Greek tēle 'far' and phōnē 'voice', the same roots as English telephone. The Spanish ending -ico works like English -ic, so telefónico means telephonic. Example: una llamada telefónica, a phone call.
