Learn Arabic (Modern Standard): بيتي بجانب المستشفى.

The word بجانب is actually made of two parts. It combines the prefix بـ (meaning "by" or "at") with the noun جانب (meaning "side"). So, saying بجانب المستشفى literally means "by the side of the hospital."

Where is the word "is" in this Arabic sentence?

In Arabic, you don't need a word for "is" or "are" in present tense sentences. You just put the subject (بيتي, "my house") right next to the information about it (بجانب المستشفى, "next to the hospital"), and the "is" is naturally understood.

Why does the word for hospital, المستشفى, end with a letter that looks like ي but has no dots?

That letter is called an alif maqsurah (ى). Even though it looks like a dotless ي, it is actually pronounced like a regular, long "aa" sound. So, the word is pronounced "al-mustashfaa".

How do we say "my" in بيتي?

In Arabic, possession is shown by attaching a suffix to the end of the noun, rather than using a separate word like "my". The word for "house" is بيت (bayt). When you add the suffix ـي (-i) to the end, it becomes بيتي (bayti), meaning "my house."
