C’est faire bouger quelque chose rapidement dans tous les sens.

The French verb "agiter" means "to shake," "to wave," or "to stir." It involves moving something back and forth or up and down quickly or energetically.

Meanings and uses:

To shake or move something quickly:
Example: Agiter une bouteille — to shake a bottle (to mix its contents).
To wave (for attention or greeting):
Example: Agiter la main — to wave the hand.
To stir up or provoke:
Agiter des idées — to stir up ideas, or agiter une foule — to stir up a crowd, meaning creating agitation or excitement.

Synonyms and nuances:

Secouer: Specifically means "to shake" something physically. "Secouer une bouteille" (Shake a bottle) is very direct and physical, focusing on the movement itself.
Difference: "Agiter" can be broader, including waving and proactive gesturing, while "secouer" focuses on shaking with force.
Remuer: Means "to stir" or "to move gently." Used often in cooking or light movement (e.g., remuer la soupe - stir the soup).
Difference: "Agiter" often implies more vigorous or noticeable movement than "remuer," which can be slow or gentle.
Brandir: Means "to wave or brandish," usually referring to weapons or objects held in an assertive or dramatic way.
Difference: "Agiter" is more neutral, can describe casual waving; "brandir" is more forceful and deliberate.

Summary:

"Agiter" is versatile — it conveys shaking, waving, or stirring, often with energy or motion intended to attract attention or cause movement. It’s more energetic or active than "remuer," more general than "secouer," and less forceful than "brandir."
