Learn Farsi: ممکن است که دولت درباره این اقدامات توضیحات بدهد. - It is possible that the government will give explanations about these measures.

Yes! The -ât suffix is a formal plural marker used specifically for Arabic loanwords, often for abstract nouns or administrative terms. The singular forms here are eghdâm (measure or action) and tozih (explanation).

Could I just use the standard Farsi plural -hâ and say eghdâm-hâ or tozih-hâ instead?

Grammatically you can, and in casual spoken Farsi, people often do use -hâ for these words. However, in formal contexts, news, or written Farsi (like this sentence discussing government actions), the -ât plural is heavily preferred and sounds much more natural.

Why does the sentence use the singular word in (this) before the plural noun eghdâmât (measures)?

In Farsi, demonstrative adjectives like in (this) and ân (that) never take a plural form when they come directly before a noun. Even though we translate it as 'these measures' in English, Farsi keeps the modifier singular: in eghdâmât.

Why is the verb bedehad (give) in the subjunctive mood here?

The subjunctive is triggered by the phrase momken ast ke (it is possible that) at the beginning of the sentence. Whenever you express doubt, possibility, or a wish, the following verb must be in the subjunctive form, which typically starts with the be- prefix.
