Etymology

Origin of smear

before 900; (v.) Middle English smeren, smirien to rub with fat, anoint, Old English smirian, smerian, smerwan; cognate with Dutch smeren, German schmieren, Old Norse smyrja, smyrwa; (noun) in current senses derivative of the v.; compare obsolete smear fat, grease, ointment, Middle English smere, Old English smeoru, cognate with Dutch smear, German Schmer, Old Norse smjǫr grease, Greek smýris rubbing powder; see emery


Explanation

To smear something is to smudge or blur it. You might literally smear your pen-and-ink drawing, or figuratively have your reputation smeared by getting caught in a lie. You can also smear things physically by smoothing them onto another surface, like when you smear lip balm on your mouth or smear cream cheese on your bagel. When you smear a person, however, you cause them real harm by hurting their reputation badly. A politician might smear an opponent by falsely claiming they lied about where they went to college, for example. That kind of smear can be hard to erase.
