What is a greek combining form?
Definition
A Greek combining form is a word part from Greek, such as tele (far), graph (write) or bio (life), that joins with others to make words like telegraph and biology.
Greek forms work differently from Latin roots. They often join to each other as equals, with no base word in charge: tele plus phone, photo plus graph, micro plus scope. That's why they are called combining forms.
They are common in science and technology vocabulary. Bio, geo, logy, meter, therm, hydro, micro, phon and scope cover a lot of what students read in science class.
Greek-origin words also bring their own spellings: ph for /f/ (phone), ch for /k/ (chorus), y for short i (gym, myth). A student who spots those spellings has a clue the word is Greek and may be built from combining forms.
In a lesson
Write telephone, microphone and phonics. The student finds phon in all three and guesses it means sound. Then they work out microscope from micro and scope.

Words come from our lexicon, checked against a pronouncing dictionary. Words a student sees in our assessments are left out.
Why does this matter for the record?
Track Greek forms alongside Latin roots but separately. Students often find Greek forms easier, because the parts are clearer.
