How the Unit 1 Word List Was Built

Your responsibility is to learn the 21 prefixes, 25 roots, and 56 suffixes in the linked tables. With these 102 parts, you can build the 346 words you will learn in this Unit. If you want to see how those words are built, this optional table will show you how it was done.

“Missing” letters (i.e. letters that have been dropped to make the word sound “better”) are indicated in square brackets.

[h]em, for example, is the root hem (blood) with the h dropped.

Combining forms (i.e. word parts that have a letter, usually an “o”, to make the word sound “better”) are indicated with slashes.

ang

angi

angio

are combined to make “ang/i/o” in its entry in the root word table.
