Question

State the rules to determine the location of the primary stress in each of the following words:i generosity ii economical iii application iv millionaire v aloud

Answer 1

Well Stress Marking doesn't have any universal rules but here are some stated by BIEAP,in their grammar book.
Note:These are not applicable for every word.

Rule1:words ending with self,ee,eer,ette,ique have stress at last syllable.
Rule 2:Words ending with ion,ial,ic,ious,eous have stress at second last syllable.
Rule 3:Words ending with ical,ian,ize,ity,logy,graphy have stress at third last syllable.
Rule 4:Words ending with silent 'r' sound have stress at first syllable.
And GENERALLY (mostly) noun has stress at first syllable and verb at second syllable.
