Regular Allomorphy

• motivated by phonetic principles

• triggered by phonetic environment

• described by modeled with phonological rules

3 types of info when write a rule for sound change process:

• Which sound are we talking about?

• How does it change?

• Where does change happen? (___Z or Z___ (before or after smth)

Method for writing allomorphy rules:

• Look at data

• Find patterns (based on sound features (voicing, place, manner(

• Write a rule(s) that apply to specific data

• Generalize rule using natural classes

Allomorphy rules practice:

anti → agonize → antagonize

meta + onomy → metonymy

auto + ism → autism

[i], [a], [o] get deleted before [i], [a], [o]

Where: at a morpheme boundary (+)

Generalize: v → ∅ / ___+ V (‘vowels delete before other vowels’)

• Total assimilation:

  • a sound takes all the features of the neighboring sounds (sound becomes an exact copy of the neighboring sound)

Phonological processes:

• Assimilation
