The phonological hierarchy (from smaller to larger units) is as follows:
- Feature
- Segment (phoneme)
- Mora (μ) ("half-syllable")
- Syllable (σ)
- Foot (F)
- P-word (ω) (prosodic or phonological word)
- Clitic group
- Phonological phrase (P-phrase)
- Intonational phrase (I-phrase)
- Utterance
From 3. Mora downwards this is also the prosodic hierarchy.
