This is the 271st most frequent Hebrew word.
מזה
"זה" translates to "this." When combined with "מ" as "מזה," it can mean "from this."
In this sentence, "מה זה" translates to "what is that" and is used to ask a question about the identity of something.
מה זה מול המראה שם?
What is that in front of the mirror there?
In this sentence, "מזה" is a slang usage in modern colloquial Hebrew translating as "so" to intensify the emotion.
אני מזה מתרגשת לקראת החופשה.
I am so excited about the vacation.
Here "מזה" again is used in a slang context to emphasize the intensity of the statement, meaning "so right" or "completely right."
