When chatting online or sending emails, I often use BTW, a short form by the way, to introduce new or additional pieces of information in text, messages, social media, or emails. It helps me digress from the current topic to add a side note naturally and informally, keeping the conversation flowing without breaking the main point, and I love how this abbreviation fits in a written context.
For instance, when planning a holiday in Florida, I hope to recommend a good hotel–BTW, this tip came from a friend’s experience. In my emails or text messages, I mention small pieces of information, making the conversation feel friendly, casual, and enjoyable.
Sharing handy tool tips keeps communication clear, smooth, and effective, allowing important details to relate to the subject without interrupting the flow.
