Words with the root word photo?
Answer Many words in the English language come to us from Latin or Ancient Greek. "Photo" is derived from Greek - the Greek word "phos" means "light." The word "graph" also comes from a Greek word meaning "to draw." A Photograph is therefore a drawing made with light. We often shortern the word "photograph" to "photo." The latin word for "light" is "lux."
Latin: Scribere = to write (gives us the root word Scrib-) I hope I understood the question correctly: you're not looking for the root word of "write"; I understand that you're looking for the root word that means write? There are other related Latin words (scriptura) that give us similar words in English (words that have the root Script-)
