The word "via" is a preposition that means "through," "by way of," or "by means of." It is used to indicate the route, method, or medium through which something happens or is done.

Examples:

• I traveled to Paris via London.
  (Meaning: I went to Paris by way of London.)

• Please send the documents via email.
  (Meaning: Send the documents by means of email.)

• She communicated the message via her assistant.
  (Meaning: She used her assistant to communicate the message.)
