❓ FAQ

How to choose between -tion and -sion?

Look at the root: if it ends in T/TE → -TION (educate→education). If it ends in D/DE/S/SE → -SION (decide→decision, confuse→confusion). If it means ‘a person’ → -CIAN.

Is -TION or -SION more common?

-TION is far more common — about 70% of ‘shun’ words use -TION. When in doubt, -TION is the safer guess.

What about -SSION words?

-SSION comes from roots ending in SS: express→expression, possess→possession, miss→mission. The double S from the root carries over.

Why does -CIAN mean a person?

-CIAN evolved from the Latin ‘-cianus’ meaning ‘relating to’. Over time, it came to specifically mean ‘a person who works with’: music→musician, politics→politician.

What about ‘pronunciation’ vs ‘pronounciation’?

It’s pronunciATION (from NUNCI, not NOUNCI). The root is ‘nunci’ (to announce), not ‘pronounce’. This is why it’s NUN not NOUN — one of the most commonly misspelled words!
