دوريتس דוריטוס Doritos transliterated in a kosher way?

Because it is a foreign word, the person who transliterated "Doritos" into Hebrew used the samech /s/ instead of the sin /s/, so that there is no question that the last sound is an /s/, and not a shin /sh/. The Arabic transliterator used the sin /s/, and leaves it to the reader to be familiar enough with the word to know that it is not "Doritosh." Neither transliteration captures the American pronunciation of the assumed plural marker at the end of the word: [z], not [s] for "s." Photo of (used) wrapper follows.

Each vowel has a color key to cue you, eg "Blue Spoon" for [u] "oo."
 

What does snowboarding have to do with grammar?

A "grammar" is a set of rules that speakers implicitly agree to use so they can understand each other. Linguists distinguish between descriptive and prescriptive grammars. Most languages have a written form and a spoken form.

A grammar does not have to describe sound or text: visual language also has a grammar and even a phonology! These hand-icons are used to establish hand-shape for an ASL word, "snow-boarding."
