Suffixes 76 words

-tion ending

Core Rule

-tion is a highly productive noun suffix in English, typically expressing an action, process, result, or state. Despite its spelling, it is almost always pronounced /ʃən/ due to historical sound reduction.

Pronunciation Guide

Start with a soft /ʃ/: tongue close to the alveolar ridge, lips slightly rounded. Glide quickly into a weak /ən/ with relaxed airflow and minimal vowel length.

Word Analysis

  • abolition: abolish + -tion, meaning “the act of abolishing,” with stress before -tion.
  • acceleration: note the reduced vowels before the suffix.
  • acidity: a contrast example showing noun formation without -tion.

Pitfalls

Avoid pronouncing it as /tɪon/. Do not confuse -tion with -sion or -cian, which follow related but distinct patterns.

Phonics Breakdown

Form /ʃ/ with the tongue near the alveolar ridge, then relax into weak /ən/.

Sound Reference

  • Memorize -tion as a single sound unit /ʃən/
  • Focus on stress placement before the suffix

Common Mistakes

Pronouncing -tion as /tion/
Treating -tion and -sion as identical
