means Fodder crop (usually grass, corn, or other greenery) that's packed tight and sealed away from air so it ferments into a preserved, edible feed for livestock.

from From French 'ensilage,' the process of storing in a 'silo' — and 'silo' itself traces back through Spanish to Latin 'sirus,' borrowed from Greek 'siros,' meaning a pit for holding grain. So the word's whole journey is literally about digging a hole and trusting it: ancient farmers stashed grain underground to keep it through winter, and the same logic — seal it away from air, let time and fermentation do the preserving — got inherited by anyone burying or bagging up grass for cattle feed millennia later.
