You may know the word for movie or film - סֶרֶט (SEH-ret). The word works both for cinematic creations as well as a ribbon, which is a kind of a film.
The word for screenplay is תַּסְרִיט (tahs-REET). Note the three-letter root embedded in the word - ס.ר.ט.
This structure - with a ת at the beginning of the word and an ee sound towards the end - occurs with many roots. For example, the root ד.פ.ס (d.p.s), which has to do with printing, creates the word תַּדְפִּיס (tahd-PEES) - printout.
