The English suffix -IST turns roots into people who do or study something: art → artist, science → scientist, journal → journalist. Across all those words the suffix sounds the same: a short, weak /ɪst/, never /aɪst/.
The Rule in One Line
-IST is unstressed. The vowel is always reduced to a short /ɪ/, almost like the I in bit, never the long I in bite. The stress stays on the same syllable as in the base word.

Why Stress Matters Here
-IST is what linguists call a stress-neutral suffix. Adding it does not move the stress. So if you already know the base word, you know the derived word:
- ART → ARTist
- JOURnal → JOURnalist
- SCIence → SCIentist
- psyCHOlogy → psyCHOlogist
- opTIcian (different suffix) vs opTOmetrist
The Most Common Mistake
The first slip learners make is pronouncing -IST like the long I in I. Words such as journalist are sometimes said as JOUR-na-LIST with stress on the suffix. Wrong. The right version is JOUR-na-list, with the suffix as a soft /ɪst/.
The -ISM Cousin
The closely related -ISM suffix follows the same rule. Both are unstressed, and the vowel is reduced. Compare:
- capital + ism → CApitalism / capitalist
- tour + ism → TOURism / TOURist
- journal + ism → JOURnalism / JOURnalist
Are There Exceptions?
Two kinds:
- Stress-attracting suffixes that come before -IST. Suffixes like -OLOGY shift the stress to the syllable before -OL-: psyCHOlogy → psyCHOlogist. The shift comes from -OLOGY, not from -IST; -IST is still unstressed.
- Words ending in -IST that are not the agent suffix. Resist, insist, persist, exist are verbs, not professions. Their -IST takes the main stress, e.g. reSIST, inSIST. Tell them apart: in agent nouns the suffix never carries the stress.

Summary
Whenever -IST turns a word into a person, the suffix is unstressed and pronounced /ɪst/. Stress stays where it was in the base word. Once you internalise this, you instantly read hundreds of profession names correctly.
