part of a circle; _orc_, the name of a fish;
_lac_, a gum or resin; and _sac_, or _soc_, a privilege, in old English
law, are ended with _c_ only. _Zinc_ is, perhaps, better spelled _zink_;
_marc, mark_; _disc, disk_; and _talc, talck_.

RULE VI.--RETAINING.

Words ending with any double letter, preserve it double before any
additional termination, not beginning with the same letter;[115] as in the
following derivatives: _wooer, seeing, blissful, oddly, gruffly, equally,
shelly, hilly, stiffness, illness, stillness, shrillness, fellness,
smallness, drollness, freeness, grassless, passless, carelessness,
recklessness, embarrassment, enfeoffment, agreement, agreeable_.

EXCEPTIONS.--1. Certain irregular derivatives in _d_ or _t_, from verbs
ending in _ee, ll_, or _ss_, (as _fled_ from _flee, sold_ from _sell, told_
from _tell, dwelt_ from _dwell, spelt_ from _spell, spilt_ from _spill,
shalt_ from _shall, wilt_ from _will, blest_ from _bless, past_ from
_pass_,) are exceptions to the foregoing rule. 2. If the word _pontiff_ is
properly spelled with two Effs, its eight derivatives are also exceptions
to this rule; for they are severally spelled with one; as, _pontific,
pontifical, pontificate_, &c. 3. The words _skillful, skillfully, willful,
willfully, chillness, tallness, dullness_, and _fullness_, have generally
been allowed to drop the second _l_, though all of them might well be made
to conform to the general rule, agreeably to the orthography of Webster.

RULE VII.--RETAINING.

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.

RULE VIII.--FINAL LL.

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, jack
