Questions & Answers about شیشهی شکسته روی کف اتاق است.
How is the word for "broken" formed here?
The word شکسته (broken) is a past participle used as an adjective. It is made by taking the past stem of the verb شکستن (to break), which is شکست, and adding the -ه (-e) ending. This perfectly matches your current lesson!
Why is there an extra letter ی at the end of شیشه (glass)?
The word شیشه ends in a silent 'h' that makes an 'e' sound. To connect it to the adjective شکسته (broken), we need an Ezafe. Because we cannot easily say two vowels back-to-back, we add ی as a bridge, pronouncing it شیشهی (shishe-ye).
Where are the hidden Ezafe vowel links in the second half of the sentence?
There are two hidden Ezafes in روی کف اتاق. The preposition روی (on) needs one to connect to the next word, pronounced ru-ye kaf. Then, to link "floor" to "room", we use another Ezafe, pronounced kaf-e otaagh. These short 'e' sounds are spoken but not written as full letters.
Can the word شیشه also be used for a glass you drink water from?
No, شیشه refers to the material of glass, a window pane, or a glass bottle. If you want to talk about a drinking glass, you should use the word لیوان.
