Frequency adverbs indicate the regularity with which an action, a state, or a habit occurs. They specify the repetition, continuity, or rarity of a fact without changing the noun or the verb. To place these forms correctly in the sentence, it is also useful to know Placement of Adverbs and Time Adverbs.

Common frequency adverbs express different degrees of regularity. Their form does not vary with gender or number, because these words are invariable. To better distinguish their formation and values, they are often compared to Formation des adverbes.

IdéeIdea	ExempleExample
Toujours indique une fréquence maximale ou une permanence selon le contexte.Always indicates maximum frequency or permanence depending on the context.	Je lis toujours avant de dormir.I always read before going to sleep.
Souvent marque une fréquence élevée mais non constante.Often marks a high but not constant frequency.	Elle étudie souvent le soir.She studies often in the evening.
Parfois exprime une fréquence irrégulière.Sometimes expresses an irregular frequency.	Nous écoutons parfois du jazz.We sometimes listen to jazz.
Rarement signale une fréquence faible.Rarely signals a low frequency.	Il prend rarement le métro.He rarely takes the metro.
Jamais exprime l absence totale de répétition.Never expresses the total absence of repetition.	Je ne mange jamais de viande.I never eat meat.

Adverbial expressions like every day or from time to time fill the same function as frequency adverbs, but they are constructed with several words. They remain stable in their form and often serve to give a more precise temporal reference. They are particularly useful when frequency must be expressed with more naturalness in everyday French, as in the usages presented in Time Adverbs.

IdéeIdea	ExempleExample
Tous les jours indique une répétition quotidienne.Every day indicates a daily repetition.	Il travaille tous les jours.He works every day.
De temps en temps indique une répétition occasionnelle.From time to time indicates an occasional repetition.	Je vais de temps en temps au café.I go to the cafe from time to time.
De manière régulière peut être précisé par une expression adverbiale.In a regular manner can be specified by an adverbial expression.	Elle court de temps en temps le matin.She runs from time to time in the morning.

In general, the frequency adverb is placed after the conjugated verb. In a compound tense, it is placed between the auxiliary and the past participle. With an infinitive, it is most often placed before the infinitive or after the main verb depending on the sentence structure. The position can vary in a more literary style or in certain regional uses, but the standard position remains the most common.

IdéeIdea	ExempleExample
L adverbe suit en général le verbe conjugué.The adverb generally follows the conjugated verb.	Elle chante souvent.She sings often.
Dans un temps composé, l adverbe se place entre l auxiliaire et le participe passé.In a compound tense, the adverb sits between the auxiliary and the past participle.	J ai toujours aimé voyager.I have always loved traveling.
Avec un infinitif, l adverbe se place souvent avant l infinitif.With an infinitive, the adverb is often placed before the infinitive.	Il aime souvent lire.He often likes to read.
Une phrase initiale peut mettre l adverbe en relief.A fronted sentence can emphasize the adverb.	Souvent, je fais du sport le matin.Often, I exercise in the morning.
L ordre peut changer selon le style ou la variété de français.The order can also vary depending on the overall structure of the sentence.	Il parle souvent avec ses amis.He often talks with his friends.

Frequency adverbs are also used in negation with ne... jamais, ne... plus or ne... rien. In everyday spoken French, ne is often omitted, but the complete structure remains the written standard. The meaning of the negation then depends on the adverb used and the context of the sentence.

IdéeIdea	ExempleExample
Ne... jamais exprime une absence totale de fréquence.Ne... jamais expresses a total absence of frequency.	Je ne mange jamais de dessert.I never eat dessert.
Ne... plus indique l arrêt d une habitude.Ne... plus indicates the stopping of a habit.	Il ne téléphone plus le soir.He no longer calls in the evening.
Ne... rien nie toute chose ou tout contenu.Ne... rien denies anything or any content.	Elle ne boit rien avant midi.She drinks nothing before noon.
Dans le français parlé, ne peut disparaître.In spoken French, ne can disappear.	Je mange jamais trop tard.I never eat too late.

Always may mean still when a situation continues, or at any moment when it expresses permanence. Context allows choosing between these two values, which should not be confused. Frequency adverbs can also modify an adjective or a state with the verb être, as in the usages described for [Adverbs of Manner], even though the meaning here concerns the duration or repetition of a state.

IdéeIdea	ExempleExample
Toujours peut vouloir dire encore.Always may mean still.	Il est toujours malade.He is still sick.
Toujours peut aussi exprimer une permanence.Always can also express permanence.	Elle est toujours calme.She is always calm.
L adverbe peut modifier un état exprimé avec être.The adverb can modify a state expressed with être.	Il est toujours fatigué.He is always tired.
Le contexte détermine le sens exact.Context determines the exact meaning.	Nous sommes toujours prêts.We are always ready.

When several adverbs occur, frequency generally precedes a short adverb of manner. Frequency adverbs remain invariable and do not take gender or number, while expressions like every day follow their own fixed construction. For other combinations and the hierarchy of complements, the presentation of [Placement of Adverbs] provides a useful guide to these rules.

IdéeIdea	ExempleExample
L adverbe de fréquence vient généralement avant un adverbe de manière court.The frequency adverb generally comes before a short adverb of manner.	Il parle souvent clairement.He often speaks clearly.
Les adverbes de fréquence sont invariables.Frequency adverbs are invariable.	Elle vient rarement.She rarely comes.
Les expressions figées gardent leur forme propre.Fixed expressions keep their own form.	Ils sortent tous les jours.They go out every day.
L ordre dépend aussi de la structure globale de la phrase.The order also depends on the overall structure of the sentence.	Je joue souvent du piano.I often play the piano.

Frequency adverbs help situate an action, a habit or a state on a scale of regularity. Their meaning depends on the context, their form does not agree, and their position varies mainly according to the verb tense and the sentence structure. Correct usage thus rests on three essential points: semantic value, syntactic position, and the stability of adverbial expressions.
