Lesson Generalization

Only a few words in the English language are formed by adding ex to a soft c or to the letter h. No words are formed by adding ex to the letter s or the letter z. The sound of /s/ or /z/ is made by the x in the prefix ex.

The prefix ex is added directly to many roots beginning with vowels. The spelling of the prefix does not change when it is joined to vowels or to the letters c and h.
