While the prefixes in 7a do not change anything in the pronunciation or shape of the base words the suffixes in 7b have such an effect. They either lead to the deletion of material at the end of the base or they lead to a different stress pattern in the examples in 7 and elsewhere primary stress is indicated by an acute accent secondary stress by a grave accent . Thus feminine loses two sounds when -ize attaches and mercury loses its final vowel when -ate is attached. The suffixes -ity -ation and -ee have an effect on the stress pattern of their base words in that they either shift the main stress of the base to the syllable immediately preceding the suffix as with -ity or attract the stress to themselves as is the case with -ation and -ee. Prefixes obviously have no effect on the stress patterns of their base words. Of course not all suffixes inflict such phonological changes as can be seen with suffixes like -less or -ness. 8 phonologically neutral suffixes -less and -ness propagánda propagándaless advénturous advénturousness radiátion radiátionless artículate artículateness mánager mánagerless openmínded openmíndedness Apart from the deletion of base material at the end of the base as in feminine -feminize suffixes can also cause the reduction of syllables by other means. Consider the difference in behavior between the suffixes -ic and -ance on the one hand and -ish For more material and information please visit Tai Lieu Du Hoc at Chapter 4 Affixation 100 and -ing on the other as illustrated with the examples in 9 .
