How to discriminate between levels 3 and 4

Level 1

Break indices of level 1 (BI 1) mark boundaries between prosodic words (PrWords). Items separated by BI 1 should carry at most one pitch accent each.

Example

Demana-ho a la Maria!
[Ask Mary!]

The clitic pronoun ho cannot bear any accent on its own and has to be combined with the verb demana to form a PrWord. So demana-ho bears only one pitch accent and constitutes a PrWord.

Similarly, neither the preposition a nor the definite article la can bear a pitch accent on their own, they need to be combined to the name Maria to form a PrWord. So a la Maria bears only one pitch accent and constitutes a PrWord.

Thus, in this sentence, there are two pitch accents, each one aligned with the stressed syllable of the two PrWords demana-ho and a la Maria, and these two PrWords are separated by a BI 1.
