Usage notes
Certain sound changes happen before the suffix, as before other derivational or inflectional suffixes beginning in. Labial stops become, dental stops  become , velar stops  become. Contracted verbs, which have stems ending in a vowel, use the long form of the vowel – this happens, for instance, in the example above: &rarr;.
