Questions & Answers about بعضی از انگورها شیرینتر هستند.
Why is "از" (from/of) used after "بعضی" (some)?
In Farsi, when you want to say "some [noun]", you generally use the phrase بعضی از (literally "some of"). So instead of saying just "some grapes", Farsi speakers say بعضی از انگورها (some of the grapes).
Since "انگورها" (grapes) are inanimate objects, shouldn't the verb be singular?
You remembered a great A1 rule! While inanimate plurals often take a singular verb, using a plural verb like هستند is also completely correct and very common. It is often used to emphasize the individual items or different varieties in a group, rather than treating them as one big single mass.
How is the word "شیرینتر" (sweeter) formed?
To make an adjective comparative (like adding "-er" or "more" in English), Farsi adds the suffix تر to the end of the word. Here, شیرین (sweet) becomes شیرینتر (sweeter).
In conversational Farsi, would people actually say the full word "هستند" here?
In everyday speech, Iranians usually combine the "to be" verb with the previous word using a short ending. Instead of saying the full written form شیرینتر هستند, you will most likely hear شیرینتَرَند.
