You already know many English words ending in -tion, -sion, and -cian, but they often sound different from how they look. The good news is that these endings follow clear patterns.
The quick rule
- -tion usually sounds like /ʃən/ (shun)
- -sion usually sounds like /ʒən/ (zhun) or /ʃən/ (shun)
- -cian usually sounds like /ʃən/ (shun)
Pattern 1: -tion = /ʃən/
Pattern 2: -sion can be /ʒən/ or /ʃən/
Most high-frequency words with -sion use /ʒən/:
A smaller group uses /ʃən/:
Pattern 3: -cian = /ʃən/
Common mistake and fix
Mistake: Saying each letter separately, like /tiː oʊ en/ at the end of a word.
Fix: Train your ear to hear one unstressed chunk: /ʃən/ or /ʒən/.
30-second practice drill
- Say each word slowly: na-tion, de-ci-sion, mu-si-cian.

Takeaway
