How to Choose the Right Alternative

Do not stack two formal phrases back to back. One polished line plus plain language reads better.
Avoid sarcastic or funny alternatives in serious conversations. Tone misfires are hard to unsend.
Match the register to the reader: professional for work, casual for friends, flirty only where it is clearly welcome.
Save two or three favorites instead of memorizing the whole list. Rotating a few keeps your wording fresh.
For texts, shorter is almost always better. Trim any alternative that takes more than one breath to say.
