Today we learnt about negative of quelque chose.

1) J'ai entendu quelque chose.
= Je n'ai rien entendu.

2) J'ai pense (passe compose) a (accent grave) tout.
=Je n'ai pense a rien.

Why is that in 1) rien is infront of the verb, and 2) is after the verb?
How do you know where to put "rien"

Thank you for using the Jiskha Homework Help Forum. The word is "learned."

To answer your question, "rien" is a negative word and it goes where "pas" goes. Je n'ai pas.....
Je n'ai rien.....

In the 2nd example you are saying "I thought OF nothing and it goes after the preposition.

Mini lesson on negatives:

ne...pas / ne...pas du tout / ne...point / ne...jamais / ne...plus / ne...guère / ne...rien / ne...personne / ne...ni...ni / ne...que / ne...aucun(aucune) / ne...nul (nulle)

1. In simple tenses, "ne" precedes the verb and pronoun objects; the 2nd part of the negative follows the verb, (or the subject pronoun in interrogative word order).
Ne vous faut-il qu'une heure?

2. In compound tenses, the 2nd part of most negatives precedes the past participle.
Elle n'avait rien dit.

3. However:
a. Personne follows the past participle (Elles n'en ont parlé à personne.)
b. Que precedes the word or words stressed, as does the word "only" in English. (Il n'a acheté que des petits pains.)
c. Each part of ni...ni precedes the word or words stressed. (L'eau n'était ni chaude ni froide.)
d. Aucun and nul precede the nouns they modify. (Cela ne posera aucun problème.)
e. Both parts of the negative generally precede the infinitive. (Il vaut mieux ne rien dire.)

4. Rien and personne may be used as subjects of the verb. Ne remains in the usual place, before the verb. (Rien n'est arrivé.)

5. Ne is used only with a verb, but the 2nd part of a negative may be usewd alone, without a verb. (Ils n'y so nt pas restés. Pourquoi pas?)

6. Jamais with a verb but without ne means "ever." (Avez-vous jamais traversé la Manche?)

7. Ne is sometimes used without pas with the verbs: cesser, oser, pouvoir, and savoir. In this case, the verb is generally followed by an infinitive. (Nous n'osons le lui dire.)

In French, the placement of the word "rien" (meaning "nothing") can vary depending on the sentence structure and verb tense. Here's how you can determine where to place "rien":

1) For sentences in the present tense or the compound past tense (passé composé), "rien" is usually placed before the verb:

- J'ai entendu quelque chose. = Je n'ai rien entendu.
Here, "entendu" (past participle of the verb "entendre") is the main verb, and "rien" directly negates it. Therefore, "rien" comes before "entendu."

2) For sentences in other tenses or with modal verbs, "rien" is typically placed after the verb:

- J'ai pensé à tout. = Je n'ai pensé à rien.
In this case, "pensé" (past participle of the verb "penser") is the main verb, and "à tout" serves as an object. When negating the verb, "rien" comes after "pensé" and "à tout" to express the idea "not thinking about anything."

The general rule is that, when negating a verb, "rien" usually comes directly before or directly after the verb, depending on the sentence structure and verb tense. It's important to pay attention to the verb and its relationship with other parts of the sentence to determine the correct placement.
