Many English multisyllable words are made up of many parts including prefixes and suffixes, and if you learn the most common prefixes and suffixes, you can expand your vocabulary dramatically. The word unpredictability has two secondary stresses as well as the main stress that is found in all English words. It’s unusual for a word to have more than one secondary stress, but this is the result of unpredictability being composed of so many parts. There are several negative prefixes in English. The most common are: de, dis, il, im, in, ir, mis, and un. This lesson will introduce you to some of them as well as helping you to pronounce them. I also look at prominence for effect. The lesson also has a crossword puzzle which will help with negative prefixes.
