Etymology
The word 'holster' entered English in the mid-17th century from Dutch. The Dutch word 'holster' is believed to be a derivative of 'holst,' meaning 'the armpit,' which itself likely comes from a Germanic root related to concealment or a hollow place. This origin story is logical, as the earliest holsters were often carried concealed under the arm or cloak. The term's journey reflects the practical need for a named, specialized case for a pistol, borrowing both the object and its name from Dutch military and civilian contexts.
Analysis
The word is a simplex loanword. Its functional role is as a complete noun.
