Boîte vs. caisse
In French, while both boîte and caisse can translate to box, they are not interchangeable. The choice between them depends mainly on the container's size, material, and purpose.
Boîte
A1Boîte is the most common and general term for box. It usually refers to a relatively small container, often with a lid, made from materials like cardboard, plastic, metal, or wood, and used for storing various items.

Caisse
A1Caisse typically describes a larger, sturdier container, like a crate or case, often made of wood, heavy cardboard, or plastic. It is frequently used for shipping, transporting goods in bulk, or for heavy-duty storage.

Summary
To summarize, think of a boîte as a general-purpose box, typically small to medium-sized (e.g., a jewelry box, a shoebox, a can of food). Think of a caisse as a larger, more robust container like a crate or case, used for transport or bulk storage (e.g., a crate of wine, a crate of apples). Additionally, remember the specific uses: boîte can mean mailbox or nightclub, while caisse very commonly refers to a checkout or cash register in a store.
