Free morpheme breakdown generator for K-12 science teachers. Break scientific words into prefix, Latin/Greek root, and suffix with a definition built from the morphemes, example sentences, and an optional printable student worksheet. No signup required.
Morphology is the study of how words are built from meaningful parts (morphemes) — prefixes, roots, and suffixes. Most scientific vocabulary is built from Greek and Latin morphemes, so teaching morphology helps students unlock the meaning of words they have never seen before by recognizing familiar parts.
A dictionary gives you the definition. This tool gives you the definition BUILT FROM the morphemes, plus the origin and meaning of each part, plus other science words that share the same parts. It is designed for teaching vocabulary as a system, not looking up individual words.
The prompts are tuned for scientific vocabulary (which is mostly Greek and Latin morphology). It will work for humanities vocabulary too, but you may get better results from tools designed for general vocabulary study.
Yes. Download a full teacher packet as a .docx file — reference table, per-word cards, and (if the student worksheet variant is enabled) a fill-in worksheet with answer key. Opens cleanly in Word and Google Docs.
The AI is instructed to split words into their actual etymological morphemes (not just orthographic splits), to name the language of origin, and to honestly say "no Greek/Latin morphology" for words like "leaf" that come from Old English. Spot-check output against Etymonline for high-stakes lessons.
