Monosyllables, and words accented on the last syllable, when they end with a single consonant preceded by a single vowel, or by a vowel after qu, double their final consonant before an additional syllable that begins with a vowel: as, rob, robbed, robber; fop, foppish, foppery; squat, squatter, squatting; thin, thinner, thinnest; swim, swimmer, swimming; commit, committeth, committing, committed, committer, committees; acquit, acquittal, acquittance, acquitted, acquitting, acquitteth.

EXCEPTIONS.—1. X final, being equivalent to ks, is never doubled: thus, from mix, we have mixed, mixing, and mixer. 2. When the derivative retains not the accent of the root, the final consonant is not always doubled: as, prefer', pref'erence, pref'erable; refer', ref'erence, ref'erable, or refer'rible; infer', in'ference, in'ferable, or infer'rible; transfer', a trans'fer, trans'ferable, or transfer'rible. 3. But letters doubled in Latin, are usually doubled in English, without regard to accent, or to any other principle: as, Britain, Britan'nic, Britannia; appeal, appel'lant; argil, argil'laus, argilla'ceous; cavil, cav'illous, cavilla'tion; excel', ex'cellent, ex'cellence; inflame', inflam'mable, inflamma'tion.
