The basic problem in learning to read words is associating semantics (what
words mean), orthography (how words are written) and phonology (how words
are pronounced). Morphology is fundamentally related to semantics, but it also
provides important clues about how words should be written and pronounced.
For example, morphology helps us know that the “un” sound at the end of
designation is not written , because it stands for the suffix.
Morphology also provides clues about how to pronounce words; for example, the
in reach represents one sound because it is within a morpheme, whereas in
react these letters represent two sounds because they are in separate morphemes.
