Notes

GENERAL INFO

Par is a preposition. It primarily means "by," "through," "per," or "for," depending on context. It indicates agent, means, movement, or distribution.

USAGE

Par commonly introduces the agent in passive sentences (*écrit par*) or indicates the means (*envoyer par la poste*). It also expresses frequency (*deux fois par semaine*) or movement through a place (*passer par ici*).

TRAPS

Don't confuse par with "pour." While both can mean "for," par implies means/agent (e.g., *payer par carte* - pay by card), whereas "pour" signifies purpose or destination (e.g., *payer pour le café* - pay for the coffee). For travel, "by car" is usually *en voiture*, not *par voiture*.
