The stressed part of each word is underlined in the table below. The pattern observed in '-ation' words is that the stress consistently falls on the 'a' before the '-tion' suffix.
| Suffix | Example Nouns |
|---|---|
| -ation | education, relaxation, imagination, immigration |
| -ion | pollution, instruction, depression, competition |
| -ment | entertainment, improvement, employment, agreement |
| -ing | running, smoking, laughing, eating |
| -ness | weakness, loneliness, happiness, kindness |
| -ity | creativity, stupidity, sensitivity, responsibility |
Observation: In '-ation' words, the stress consistently falls on the syllable before '-ation'. For other suffixes, the stress placement varies, often falling on a syllable before the suffix, but not as predictably as in '-ation' words.
