RULES FOR SPELLING.

Words ending in _e_ drop that letter before the termination _able_,
as in move, movable; unless ending in _ce_ or _ge_, when it is
retained, as in change, changeable, etc.

Words of one syllable, ending in a consonant, with a single vowel
before it, double the consonants in derivatives; as, ship, shipping,
etc. But if ending in a consonant with a double vowel before it, they
do not double the consonant in derivatives; as, troop, trooper, etc.

Words of more than one syllable, ending in a consonant preceded by a
single vowel, and accented on the last syllable, double that consonant
in derivatives; as, commit, committed; but except chagrin, chagrined.

All words of one syllable ending in _l_, with a single vowel before
it, have _ll_ at the close; as mill, sell. All words of one syllable
ending in _l_, with a double vowel before it, have only one _l_ at the
close; as mail, sail.

The words foretell, distill, instill and fulfill, retain the _ll_
of their primitives. Derivatives of dull, skill, will and full also
retain the _ll_ when the accent falls on these words; as dullness,
skillfull, willfull, fullness.

Words of more than one syllable ending in _l_ have only one _l_ at the
close; as delightful, faithful; unless the accent falls on the last
syllable; as befall, etc.

Words ending in _l_, double the letter in the termination _ly_.

Participles ending in _ing_, from verbs ending in _e_, lose the final
_e_; as have, having; make, making, etc; but verbs ending in _ee_
retain both; as see, seeing. The word dye, to color, however, must
retain the _e_ before _ing_. All verbs ending in _ly_, and nouns
ending in _ment_, retain the _e_ final of the primitives; as brave,
bravely; refine, refinement; except words ending in _dge_; as,
acknowledge, acknowledgment.

Nouns ending in _y_, preceded by a vowel, form their plural by adding
_s_; as money, moneys; but if _y_ is preceded by a consonant, it is
changed to _ies_ in the plural; as bounty, bounties.

Compound words whose primitives end in _y_, change the _y_ into _i_;
as beauty, beautiful.

THE USE OF CAPITALS.

Every entire sentence should begin with a capital.

Proper names, and adjectives derived from these, should begin
