Is Bagpack a Different Type of Bag?

The Origin of Bagpack or Backpack
The word backpack is a compound made from back and pack. Its meaning is quite direct: a pack that is carried on the back.
Etymonline dates backpack to around 1904 in the sense of a bag with shoulder straps that can be carried on the back. It also records back-pack as an earlier written form.
Merriam-Webster gives 1897 as the first known use of backpack as a noun and 1899 for the verb.
The spelling bagpack likely develops from a simple word association. People see the object as a bag, so “bag + pack” may feel natural. But the standard English word is backpack, because the important feature is where the pack is carried.
The older hyphenated form back-pack can appear in historical writing, but modern English normally uses the closed form backpack.
