More round or circular in shape; having a more curved or spherical form.
From Old English 'rund,' likely from Old Norse 'runnr.' The comparative form adds the suffix '-er' to show greater degree of roundness.
The letter 'o' sounds round when you say it—that's not a coincidence but rather how humans intuitively match sounds to shapes. When we describe something as 'rounder,' we're using the same sound that gives us the shape, which linguists call 'sound symbolism.'
