Learn Farsi: در این نسخه‌ی خطی نایاب، یک خط‌خوردگی نیز پذیرفتنی نیست. - In this rare manuscript, not even one crossing-out is acceptable.

This is the core of emphatic scalar negation. By combining یک (one), the noun خط‌خوردگی (crossing-out), the formal word نیز (also/even), and the negative verb نیست (is not), you get the literal meaning "one crossing-out also is not". In natural English, this translates to "not even one crossing-out is...". It emphasizes that the absolute minimum amount is still rejected.

What is the literal translation of نسخه‌ی خطی (manuscript)?

Literally, it means "handwritten copy". The word نسخه means "copy" or "version" (also commonly used for a medical prescription), and خطی means "handwritten" or "linear" (from خط, meaning "line" or "handwriting"). They are linked by the ezāfe to form the standard Farsi term for a manuscript.

How is the compound noun خط‌خوردگی (crossing-out) built?

It is formed from خط (line) and the verb خوردن (which can mean to strike, hit, or suffer). A خط‌خورده is a word that has been crossed out (literally "line-struck"). By adding the suffix گی, which turns adjectives or participles into abstract nouns, we get خط‌خوردگی, meaning an erasure or the state of being crossed out.

How does the suffix at the end of پذیرفتنی (acceptable) change the word?

Adding ی to the end of a Farsi infinitive creates an adjective of worthiness, capability, or possibility. Here, it is attached to the infinitive (to accept). So, literally means "worthy of being accepted" or "acceptable". This is the same structure used in familiar words like (worth seeing) or (edible).
