IPA: /ˈlændlaɪn/
KK: /ˈlændˌlaɪn/
A type of telephone that is connected to the phone network by a physical wire, usually found in homes and offices.
I still use a landline for my home phone because it has a clearer connection than my mobile phone.
Landline → It is formed from "land" (from Old English *land*, meaning ground or soil) and "line" (from Latin *linea*, meaning a string or line). The word "landline" refers to a telephone line that is physically connected to the ground or land, as opposed to a mobile or wireless connection.
Think of 'land' as the ground and 'line' as a connection — a landline is a connection that is physically tied to the ground.
