Relating to or affecting only one side of the tongue.
From 'hemi-' (half) + 'glossal' (relating to the tongue, from Greek 'glossa'). This medical term describes conditions that involve only the left or right side of the tongue.
Hemiglossal paralysis is a telltale sign of a stroke—when someone can't stick their tongue straight out because one side is weak, doctors know exactly which brain hemisphere got hit!
