Here is an example of an application of lexical phonology:
Here are the words to be considered in this example:
- sane [sejn] / sanity [sQnIti]
- neighbor [nejb«&u0279;] / neighborhood [nejb«&u0279;hUd] *[nQb«&u0279;hUd]
The following rule applies across level 1 morpheme boundaries:
- A tense vowel becomes lax when a short word is lengthened by adding a suffix, so that the words ends up having at least three syllables.
