French For Football/Grammar/Adverbs

French adverbs, like their English counterparts, are used to modify adjectives, other adverbs, and verbs or clauses. They do not display any inflection; that is, their form does not change to reflect their precise role, nor any characteristics of what they modify.

Formation
In French, as in English, many adverbs are derived from adjectives. In most cases, this is done by adding the suffix -ment (English "-ly") to the adjective's feminine singular form. For example, the feminine singular form of lent ("slow") is lente, so the corresponding adverb is lentement ("slowly"); similarly, malheureux → malheureusement ("unhappy" → "unhappily").

As in English, however, the adjective stem is sometimes modified to accommodate the suffix:


 * If the adjective ends in an i, then -ment is added to the masculine singular (default) form, rather than to the feminine singular form:
 * vrai → vraiment ("real" → "really")
 * impoli → impoliment ("rude" → "rudely")
 * If the adjective ends in -ant or -ent, then the corresponding adverb ends in -amment or -emment, respectively:
 * constant → constamment ("constant" → "constantly")
 * récent → récemment ("recent" → "recently")
 * Some adjectives make other changes:
 * précis → précisément ("precise" → "precisely")
 * gentil → gentiment ("nice" → "nicely")

(Look out though, as the -ment suffix is also used to create nouns from verbs where it then corresponds with English -ing.)

Some adverbs are derived from adjectives in completely irregular fashions, not even using the suffix -ment:
 * bon → bien ("good" → "well")
 * mauvais → mal ("bad" → "badly")
 * meilleur → mieux ("better"-adjective → "better"-adverb)
 * pire → pire ("worse"-adjective → "worse"-adverb)

And, as in English, many common adverbs are not derived from adjectives at all:
 * ainsi ("thus" or "thusly")

Placement
The placement of French adverbs is almost the same as the placement of English adverbs.

An adverb that modifies an adjective or adverb comes before that adjective or adverb: An adverb that modifies an Infinitive (verbal noun) generally comes after the infinitive: But negative adverbs, such as pas ("not"), plus ("not any more"), and jamais come before the infinitive:
 * complètement vrai ("completely true")
 * pas possible ("not possible")
 * tellement discrètement ("so discreetly")
 * marcher lentement ("to walk slowly")
 * ne pas s'affoler ("don't panic")

An adverb that modifies a main verb or clause comes either after the verb, or before the clause: Note that, unlike in English, this is true even of negative adverbs:
 * Lentement il commença à marcher or Il commença lentement à marcher ("Slowly, he began to walk" or "He began slowly to walk").
 * Jamais je n'ai fait cela or Je n'ai jamais fait cela ("Never have I done that" or "I've never done that")
