What does swabbed mean?
Swabbed is the past tense and past participle of swab, a verb meaning to clean or wipe something with a small absorbent material. It is especially common in medical, laboratory, and forensic settings, where a swab may be used to clean a site or to collect a sample for examination. The word can also describe ordinary cleaning, such as swabbing a table or countertop with a damp cloth, although it often conveys a more precise or methodical action than simply wiping. In its medical sense, swabbing a wound or body surface can remove contaminants, apply a substance, or gather material for testing. The double final consonant is a standard feature of English spelling when a verb ending in a single consonant is stressed and suffixed with -ed.
