Background & History
Like many internet abbreviations, “LYK” originated in the early 2000s, during the rise of SMS texting. Back then, character limits were tight—just 160 characters per message. To save space and time, people started using short forms such as “u” for “you,” “brb” for “be right back,” and “lyk” for “let you know.”
As technology evolved, the abbreviation carried over to social media platforms like Facebook, Twitter, and Instagram. Even today, “LYK” remains popular among younger generations who love quick, efficient ways to communicate. Although it’s not as formal or common as “LMK” (let me know), it still holds a place in modern online language.
