Words ending with any double letter, preserve it double in all derivatives formed from them by means of prefixes: as, see, foresee; feoff, enfeoff; pass, repass; press, depress; miss, amiss; call, recall; stall, forestall; thrall, inthrall; spell, misspell; tell, foretell; sell, undersell; add, superadd; snuff, besnuff; swell, overswell.

OBSERVATION.—The words enroll, unroll, miscall, befall, befell, bethrall, reinstall, disinthrall, fulfill, and twibill, are very commonly written with one l, and made exceptions to this rule; but those authors are in the right who retain the double letter.
