Repository Vs Depository?????????Do They Mean Different Things?

Repository comes from the 15th century French word repositoire meaning ‘placed back.’ (I always think 'repose,’ as in something resting in storage) Repository is a more common word than depository - generally because it’s 200 years older - and it means a place where things are stored.
More specifically, you can use the word repository to describe a place where significant items are stored, such as pieces of art, important documents and artifacts.
I would also use repository in a metaphorical sense. For example in my circle of friends, I’m known (rather flatteringly) as the person who usually knows what unusual or obscure words mean. In other words, to them, I am a repository of word definitions.
