Teaching Notes.

Watch the Middles. In differ the prefix dif- is a form of dis- and means “apart.” The base fer means “carry, bear” and occurs in words like conference, defer, referee, suffer.

In touches -es is a form of the suffix -s, which students will study in Book Two.

In toward to is the preposition to; ward is a suffix meaning “in a specified direction.”

In between be- is the prefix that indicates position near or at; tween occurs only in the rare tween, tweeny, meaning an older pre-teenager, a word formed from between. In between the base tween carries the meaning “two” and is related to several other <tw> words containing the meaning “two”: two, twelve, twenty, twin, twilight, etc.
