To take a round form, se rotundare, or rotundari; conglobari; conglobari undique aequaliter. A round number, numerus par (equal number): solidum (a whole). A good round sum, magna pecuniae summa, or nummi non mediocris summae.

Often by circum in composition: to ride round, circumequitare or equo circumvehi (locum): to roll round, circumvolvere (transitively), circumvolvi (intransitively).

Figuratively, to round a sentence, sententiam, ordine verborum paullo commutato, in quadrum redigere (Cic., Or., 70, 233). The rounding of a sentence, verborum apta et quasi rotunda constructio; structura (☞ not circumscriptio in this sense): rounded, rotundatus (made round): rotundus (round): conglobatus (like a ball): figuratively, of speech, quasi rotundus.
