Final ll is peculiar to monosyllables and their compounds, with the few derivatives formed from such roots by prefixes; consequently, all other words that end in l, must be terminated with a single l: as, cabal, logical, appal, excel, rebel, refel, dispel, extol, control, mogul, jackal, rascal, damsel, handsel, tinsel, tendril, tranquil, gambol, consul.

OBSERVATION.—The words annul, until, distil, extil, and instil, are also properly spelled with one l; for the monosyllables null, till, and still are not really their roots, but rather derivatives, or contractions of later growth. Webster, however, prefers distill, extill, and instill with ll; and some have been disposed to add the other two.
