Etymology
Origin of container
1400–50 for an earlier sense; 1495–1505 container for def. 1; late Middle English conteiner; see contain, -er 1
Explanation
A container holds things inside it. Bags, boxes, buckets, and pockets are all containers. The purpose of a container is to carry, hold, or store something. You might buy nuts at the grocery store, then bring them home and put them in a container, or you could put your leftover pasta in an airtight container and store it in the refrigerator for tomorrow's lunch. The thing all containers have in common is that they contain, or hold, things. Both words are rooted in the Latin continere, "to hold together or enclose."
