s are formed adjectives of plenty, by adding the
termination ful, denoting abundance; as, joy, joyful; fruit, fruitful;
youth, youthful; care, careful; use, useful; delight, delightful; plenty,
plentiful; help, helpful.

Sometimes in almost the same sense, but with some kind of diminution
thereof, the termination some is added, denoting something, or in some
degree; as delight, delightsome; game, gamesome; irk, irksome; burden,
burdensome; trouble, troublesome; light, lightsome; hand, handsome; alone,
lonesome; toil, toilsome.

On the contrary, the termination less added to substantives, makes
adjectives signifying want; as, worthless, witless, heartless, joyless,
careless, helpless. Thus comfort, comfortless; sap, sapless.

Privation or contrariety is very often denoted by the participle un
prefixed to many adjectives, or in before words derived from the Latin; as
pleasant, unpleasant; wise, unwise; profitable, unprofitable, patient,
impatient. Thus unworthy, unhealthy, unfruitful, unuseful, and many more.

The original English privative is un; but as we often borrow trom the
Latin, or its descendants, words already signifying privation, as
inefficacious, impious, indiscreet, the inseparable particles un and in
have fallen into confusion, from which it is not easy to disentangle
them.

Un is prefixed to all words originally English, as untrue, untruth,
untaught, unhandsome.

Un is prefixed to all participles made privative adjectives, as
unfeeling, unassisting, unaided, undelighted, unendeared.

Un ought never to be prefixed to a participle present to mark a
forbearance of action, as unsighing, but a privation of habit, as
unpitying.

Un is prefixed to most substantives which have an English termination,
as unfertileness, unperfectness, which, if they have borrowed
terminations, take in or im, as infertility, imperfection; uncivil,
incivility; unactive, inactivity.

In borrowing adjectives, if we receive them already compounded, it is
usual to retain the particle prefixed, as indecent, inelegant,
improper; but if we borrow the adjective, and add the privative
particle, we commonly prefix un, as unpolite, ungallant.

The prepositive particles dis and mis, derived from the des and mes of the
French, signify almost the same as un; yet dis rather imports contrariety
than privation, since it answers to the Latin preposition de. Mis
