means The highest title in chess, awarded for lifetime achievement at the board — earned through specific norms and ratings, and once given, never taken away.

from Chess borrowed the structure of 'master' titles from older guild and craft traditions, where a 'master' had proven full command of a trade — the 'grand' simply stacked on top to mark the apex above ordinary mastery. The specific title 'Grandmaster' was formalized by the international chess federation (FIDE) in the 1950s to standardize what had been an informal honorific used loosely for top players since the early 1900s, reportedly even applied by a Russian tsar to a handful of elite competitors at a tournament — a charming story often repeated, though the historical details of that tale are thin and not fully verifiable.
