Answer:
naw
Step-by-step explanation:
The primary accented syllable is a syllable that is focused most of all when the word is spoken. For example: when we say Fatastic, the syllable that is focused most is tas.
If we see the syllables of endocrinology, there can be following few options for a primary syllable.
en-doh-krih-loh-jee: This is not most focused accented syllables, so these are not primary syllable.
naw: This is most focused syllable so this is primary accented syllable.
