Questions & Answers about خانهی سگ تمیز است.
Why is there a ی added to the end of خانه?
The word for house, خانه (khane), ends in a silent 'h' which produces an 'e' vowel sound. When we link a word ending in a vowel to its owner, the Ezafe particle becomes -ye (written as ی) instead of the usual -e. This prevents two vowels from clashing and makes it easier to say.
In English we say "dog's house". Why are the words in the opposite order here?
In Farsi, you don't use an "apostrophe-s" to show ownership. Instead, the thing being owned always comes first, followed by the Ezafe particle, and then the owner. You can think of the Ezafe as the word "of", so خانهی سگ literally translates to "house of dog".
The English translation says "The dog's house", but I don't see a word for "the". How do we know it's there?
Farsi does not have a specific word for "the". Instead, a noun is understood to be definite (specific) based on the context of the conversation. Since this sentence describes a specific house being clean, we naturally translate it with "the" in English.
Why is the word است (ast) at the very end of the sentence?
In Farsi, the main verb almost always goes at the very end of the sentence. The structure here is Subject + Adjective + Verb, so it literally reads as "[The house of dog] [clean] [is]".
