The correct spelling of the word is "syntax", pronounced /ˈsɪntæks/. The word refers to the arrangement of words and phrases to create well-formed sentences in a language. The "sy" in syntax is pronounced /s/, not /z/, due to the fact that it originates from Greek where the combination "sy" always represents /s/. So if you see the word "sintax", remember to spell it as "syntax" to correctly convey your message.
