What is by the way?

By the way is an English phrase that serves as a conversational filler, a transition, or a means of introducing related but slightly off-topic information. It signals a shift in the conversation's direction, often to something that the speaker has just remembered or feels is relevant.

• Function: It primarily serves to introduce an aside or tangential point into a conversation. Think of it as a verbal "addendum." (See: https://www.wikiwhat.page/kavramlar/Conversational%20Fillers)

• Usage: It can be used to:

  • Introduce a new, related topic.
  • Provide additional information that might be helpful to the listener.
  • Change the subject subtly. (See: https://www.wikiwhat.page/kavramlar/Subject%20Change)
  • Add a forgotten detail.

• Alternatives: Depending on the specific context, other phrases could be used in its place, such as "incidentally," "on a related note," "speaking of which," or simply "oh, and."

• Formality: The phrase "by the way" is generally considered informal and suitable for casual conversations. (See: https://www.wikiwhat.page/kavramlar/Informal%20Language) In more formal settings, a more appropriate phrase might be required.
