Frequently Asked Questions

What does the suffix -ist mean?

The suffix -ist names a person who does, makes or studies something. An artist makes art, a cyclist rides a bike, a pianist plays the piano and a violinist plays the violin. Because the base word is often easy to find, -ist words are a good way to show children how a suffix adds meaning to a word they already know.

Is -ist a Greek or Latin suffix?

The suffix -ist started in Greek, then passed into Latin and French before reaching English. That long history is why it attaches to so many kinds of base words, from art to piano and violin. For young readers, the history matters less than the pattern: find the base word, read the ending and put the two together.

How do you know whether a word ends in -er or -or?

Both the -er and -or suffix can mean a person who does something, and there is no rule that works every time. The ending -er is far more common and is added to everyday verbs: teach becomes teacher, bake becomes baker and ride becomes rider. The ending -or turns up more often in words from Latin, such as actor, visitor, editor and inventor, so those are worth meeting often in stories.

What -er, -or and -ist words do the stories use?

The books for UFLI Lesson 121 include words like baker, rider, writer, dancer and teacher, actor, doctor, sailor and visitor, and artist, dentist and florist. Talking about who does what in the story helps children link each ending to its meaning. Bus, van IJzendoorn and Pellegrini (1995) found that reading books together is linked with stronger language growth and early literacy.
