I found writing Thai to be not so difficult to learn. It uses an alphabet, although it does have more letters than English and some tone marks. But it is very regular and pronunciation is consistent. I haven&#x27;t studied Vietnamese but at first glance it seems not much easier than learning the Thai alphabet. Learning tones is difficult, as you said. I couldn&#x27;t even hear them at first - the words for &quot;news&quot;, &quot;rice&quot; and the color &quot;white&quot; all sounded the same to me. Trying to put together sentences resulted in some hilarity when I mixed up tones for words that differ only in tone like &quot;dog&quot;, &quot;horse&quot; and &quot;come here&quot;.<p>Question: How many consonants, vowels and tone marks in Vietnamese?
