How to do it
- Check whether the word refers to time; the conjunction “seit” (“since”) introduces a clause about time.
- If it has a time meaning, write “seit”.
- For “seid” (a form of “sein”, to be), the rule doesn't apply.
Why it works
The conjunction “seit” introduces a temporal clause, so the rule only fits time meanings.

Die Konjunktion seit leitet einen temporalen Nebensatz ein. Aus diesem Grund hat sich der Merksatz „seit bei Zeit“ durchgesetzt.
