Some basic rules on stress :
1.Stress is placed on the root word. Suffixes and prefixes are not stressed.
Mis, dis and un are not stressed because they are prefixes.
al too is not stressed because it is a suffix.
Regardless of whether the word is used as a noun or verb eg mis.use the first syllable cannot be stressed because it’s an affix(prefix/suffix)
NB:Throughout this long write up, the full stop indicates syllable boundary.
2.Stress falls on the syllable with a diphthong eg prosecute
Pro. se. cute
Pro is stressed because it has a diphthong /ou/
3.Stress falls on the syllable with the long vowel sound agreement, markbook
- gree. ment
gree is stressed because it contains a long vowel sound double e=/i:/
Mark is stressed because it has a long vowel sound ar =/a:/
Book has a short vowel sound double o in book produces the short o
4.In words containing suffix -ic, stress falls on the penultimate, second last syllable.you count from your right, the last syllable being ic

Stress falls on buse, larm and dition, the longer syllables.
Regardless whether the word is used as a noun or verb, the second, longer syllable is stressed.
6.In words that have double consonants
You stress the longer syllable that remains after the boundary or that remains with the double consonants ,which will be the second syllable.
NB:There are exceptions to this rule :
The stress in the words above is on Col and chal though they are the shorter syllable and don’t have the double consonants.
