Every medical word is a root naming a structure, a suffix saying what is happening to it, an optional prefix adjusting position or degree, and a combining vowel holding it together. Pick parts from the four menus and watch the word assemble itself — then switch to Build to order and construct the term a chart would actually use.
Prefix optional · position, number, time, degree
Word root required · names the structure
Second root optional · long terms list roots in anatomical order
Suffix required · decides what kind of word this is
Your term, part by part
Choose a root and a suffix to begin. A root alone is not a word — you never say “cardi” or “nephr.”

Where the combining vowel went
Nothing built yet. The vowel — almost always o — exists only to make the joint pronounceable, so it appears and disappears according to what sits on either side of it.
