## AI Etymology
Swab is traced through back-formation from swabber, from Middle Dutch swabber ('mop') and Middle Low German swabben ('to swab, mop'), ultimately from Proto-Germanic; entering Early Modern English as a cleaning tool and the act of cleaning. In current use it is a noun and verb meaning "a small piece of absorbent material used for cleaning or taking samples". That sense is explained by the older material without requiring a speculative semantic step: the inherited or borrowed base supplies the field of meaning, while the English formation fixes its modern role. The history is mainly one of transmission into English, with the older form and sense carried through borrowing or adaptation. For dictionary purposes, the important point is the continuity between the older form, the route into English, and the present lexical sense.
