Etymology
The word 'doorstop' is a transparent endocentric compound from Modern English, formed by directly combining two native elements. The first element, 'door', descends from the Proto-Germanic dur-, which can be traced back to the Proto-Indo-European root dhwer- meaning "doorway, gate, courtyard." The second element, 'stop', entered English from Latin via Old English, with its core sense of "to block or prevent movement." The compound's logic is entirely literal and functional: an object whose purpose is to stop a door. This straightforward morphological construction reflects a common pattern in English for naming tools by stating their object and function, resulting in a meaning that is precisely the sum of its parts.
Analysis
Structure: door + stop
door: From Old English duru/dor, meaning "door, gate, passage." It is a common Germanic noun functioning as the base object in the compound.
stop: From Old English stoppian (to stop, close a hole), via Latin stuppāre (to plug with tow). In this compound, it functions as an action/function specifying the purpose related to the base object.
