How to Choose the Right Alternative

  1. Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
  2. Adjust one word to make it yours: swap a name, a detail, or a reference only the two of you share.
  3. Do not stack two formal phrases back to back. One polished line plus plain language reads better.
  4. For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
  5. Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
