montón
/monˈton/ · A2 · noun · m
pile
⛰️ montón = monte (mount) + -ón (big): a big mound, so a ton of stuff
From monte (mountain, mount) plus the augmentative suffix -ón, which makes things bigger. A montón is literally a big mount of things, and by extension a lot of anything. The ending even sounds like English ton: un montón = a ton.
