Throng.
Synonyms:
concourse, crowd, host, jam, mass, multitude, press.
A crowd is a company of persons filling to excess the space they occupy and pressing inconveniently upon one another; the total number in a crowd may be great or small. Throng is a word of vastness and dignity, always implying that the persons are numerous as well as pressed or pressing closely together; there may be a dense crowd in a small room, but there can not be a throng. Host and multitude both imply vast numbers, but a multitude may be diffused over a great space so as to be nowhere a crowd; host is a military term, and properly denotes an assembly too orderly for crowding. Concourse signifies a spontaneous gathering of many persons moved by a common impulse, and has a suggestion of stateliness not found in the word crowd, while suggesting less massing and pressure than is indicated by the word throng.
