No, French does not conjugate adverbs. Unlike verbs, which change based on tense, or adjectives, which agree in gender and number, adverbs remain invariable—they do not change regardless of the subject, verb tense, or noun they modify.

Key Characteristics of French Adverbs

✔ Fixed form – Adverbs do not change (e.g., vite (fast), bien (well), lentement (slowly)).
✔ Modify verbs, adjectives, or other adverbs – Example: Elle parle doucement. (She speaks softly.)
✔ Often formed from adjectives – Many adverbs are created by adding "-ment" to the feminine form of an adjective.

Examples of Adverbs in French

1. Adverb modifying a verb:
   • Il marche lentement. (He walks slowly.)
2. Adverb modifying an adjective:
   • C'est très intéressant. (That’s very interesting.)
3. Adverb modifying another adverb:
   • Il parle trop vite. (He speaks too fast.)

Since adverbs don’t change, you never have to worry about making them agree in gender or number, unlike adjectives.

The Spanish language was not "invented" by a single person but rather evolved over time. It originated from Vulgar Latin, the common form of Latin spoken by the Roman Empire’s soldiers and settlers who occupied the Iberian Peninsula (modern-day Spain and Portugal) after the 3rd century BCE.
