The greatest difficulty with the Siamese language lies in the tonal system.
His numerical table, therefore, differs from all others made before or since, prophetically assigning the place of honour to the one ancient scale now recognized as the foundation of the modern tonal system.
A complication is caused by the fact that the consonants are grouped into three classes, to each of which a special tone applies, and consequently the application of a tonal sign to a letter has a different effect, according to the class to which such letter belongs.
Of such monosyllables there are less than two thousand, and therefore many syllables have to do duty for the expression of more than one idea, confusion being avoided by the tone in which they are spoken, whence the term" tonal,"which is applied to all the languages of this family.
The term "language", includes verbal, tonal and body languages, which underpin all cultural learning structures.
