Word Stress in Russian

Here we will be speaking only about the word stress since there is also the logical stress which accentuates certain word in a sentence. The word stress is a way of differentiating the certain syllable of the word from the others by various means. Generally there are four types of stress:
quantitative - the length of the vowel of the stressed syllable is longer than the lengths of unstressed vowels
dynamic - the stressed syllable is more powerful, intensive and loud in pronunciation, sometimes this type is falsely called expiratory since the strength of the syllable is thought to depend on the amount of exhaled air, but these are different phenomena not determining each other
