means A storage space behind or near a shop where extra inventory is kept until it's needed on the sales floor.

from A straightforward compound: 'stock,' meaning goods kept on hand for sale or use (itself rooted in Old English 'stocc,' a tree trunk or stump, which widened over centuries into 'store of goods'), plus 'room,' a space within a building. No hidden story here — the word simply names its job, which is also why it's stuck around unchanged since 'stock' took on its retail sense.
