phone
Transitive Verb[C] Countable
pl: phonespp: phoneding: phoning
The term has evolved from a technical description of a telephonic apparatus to a synonym for a handheld computer. In modern conversation, it almost exclusively refers to a smartphone, carrying a connotation of constant connectivity and digital dependency. Using the word as a verb is more common in British English than American English, where call is the preferred term. It suggests a direct, intentional act of communication rather than a casual text or a digital message.
Countable when referring to the physical device you hold in your hand.
