Usage: Use this verb when describing the act of tightly filling a container, often implying that items are being crowded in without regard for neatness. It is commonly used informally rather than in formal writing where more precise terms like "pack" or "fill" might be preferred.
The word "stuff" comes from the Middle English term for filling or equipping something, which traveled into English via Medieval Latin and Old French. Its ultimate origin is an ancient Germanic root meaning to clog up, block, or fill a space.
