I assume you are both referring to "SYNTAX" rather than syntex. It means the relationship between words and phrases as used in a sentence. " Throw me down the stairs my hat", is funny only because the syntax is all wrong, when the person actually means to say, " Throw my hat down the stairs to me. " Some people will purposely mispell a word, or make a letter in their business name backwards just to get people to notice their business and stop by if only to tell them their sign is misspelled. Better than being the Maytag Repairman, I guess. The same thing is now commonly done with syntax. Now that more than 1/2 of the people in the USA have some college education, this is the new " hook " being used by some advertisers to gain an audience. In other cases, the owners don't know better. Either way, it brings in the customers.
