ble; 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_. See Observations 13
and 14, p. 199.

RULE IV.--NO DOUBLING.

A final consonant, when it is not preceded by a single vowel, or when the
accent is not on the last syllable, should remain single before an
additional syllable: as, _toil, toiling; oil, oily; visit, visited; differ,
differing; peril, perilous; viol, violist; real, realize, realist; dial,
dialing, dialist; equal, equalize, equality; vitriol, vitriolic,
vitriolate_.

EXCEPTIONS.--1. The final _l_ of words ending in _el_, must be doubled
before an other vowel, lest the power of the _e_ be mistaken, and a
syllable be lost: as, _travel, traveller; duel, duellist; revel, revelling;
gravel, gravelly; marvel, marvellous_. Yet the word _parallel_, having
three Ells already, conforms to the rule in forming its derivatives; as,
_paralleling, paralleled_, and _unparalleled_. 2. Contrary to the preceding
rule, the preterits, participles, and derivative nouns, of the few verbs
ending in _al, il_, or _ol_, unaccented,--namely, _equal, rival, vial,
marshal, victual, cavil, pencil, carol, gambol_, and _pistol_,--are usually
allowed to double the _l_, though some dissent from the practice: as,
_equalled, equalling; rivalled, rivalling; cavilled, cavilling, caviller;
carolled, carolling, caroller_. 3. When _ly_ follows _l_, we have two Ells
of course, but in fact no doubling: as, _real, really; oral, orally; cruel,
cruelly; civil, civilly; cool, coolly; wool, woolly_. 4. Compounds, though
they often remove the principal accent from the point of duplication,
always retain the double letter: as, _wit'snapper, kid'napper,[114]
grass'hopper, duck'-legged, spur'galled, hot'spurred, broad'-brimmed,
hare'-lipped, half-witted_. So, _compromitted_ and _manumitted_; but
_benefited_ is different.

RULE V.--FINAL CK.

Monosyllables and English verbs end not with _c_, but take _ck_ for double
_c_; as, _rack, wreck, rock, attack_: but, in general, words derived from
the learned languages need not the _k_, and common use discards it; as,
_Italic, maniac, music, public_.

EXCEPTIONS.--The words _arc_,
