linebacker
UK: ˈlaɪnˌbækə | US: ˈlaɪnˌbækər
n. (American football) a defensive player positioned behind the line of scrimmage, responsible for tackling runners and covering receivers.
The term "linebacker" emerged in early 20th-century American football, combining "line" (referring to the scrimmage line) and "back" (indicating a position behind it). The "-er" suffix denotes the player’s role. Originally describing defensive players positioned between the linemen and secondary, the word reflects the sport’s tactical evolution, where these athletes "back" the defensive line while remaining mobile.
