But there are suffixes that change the stress in longer words.
Educate – education
When we add the suffix –ion or –ian, the stress always moves to the syllable before these suffixes.
Electric – electrician, decorate – decoration
The ending –ic also moves the stress to the syllable before it.
Scientist – scientific, economy – economic, artist – artistic
The ending –al doesn’t change the stress of the word.
Economy – ………… - economical
