The -er and -est endings

Both are unstressed, so -er is /ər/ rather than the /ɜːr/ of her. The same ending also makes agent nouns: teacher, farmer, baker.

Where Wiggler teaches it: Skill 13: Suffixes

Child explanation

Big, bigger, biggest. The -er and -est bits are quiet — you do not say them loudly.

The rule

-er and -est are unstressed suffixes. -er makes comparatives (bigger) and agent nouns (teacher); -est makes superlatives. Both reduce to schwa-like vowels.

What is really going on

Two distinct morphemes sharing a spelling: the comparative -er and the agentive -er. Both are unstressed and both reduce, so for reading they behave identically. The doubling and y-to-i changes apply as with -ing and -ed.

Contrast pairs

Teacher note

Point out that the -er in teacher and the -er in bigger look the same and mean quite different things. That is a child's first useful encounter with the idea that spelling encodes meaning rather than only sound, and it prepares the ground for prefix work.
