The stress on the first syllable is also primary, but it is effected by pronouncing the syllable on a high level pitch. This syllable bears the pre–nuclear primary accent.

The stress on the third syllable is weaker and is called secondary. It is effected by pronouncing the syllable on a mid–level pitch.
