Karan Inside Longer Words
The karan mark from your last two mornings belongs to just one syllable, not to the whole word. Instead of stopping at the mark, you finish that one syllable and keep reading.
I think อาทิตย์, Sunday, is the clearest place to feel it. Its first syllable อา is plain and mid. In ทิตย์ you cross out the ย under the mark, so ต becomes the final, the syllable goes dead, and because ท is low class you still have to check the vowel. That vowel is short, so the tone is high. It is แพทย์ turned inside out, with the same low class and the same dead ending after the deletion, but แพทย์ had a long vowel and fell, while ทิตย์ stays short and goes high.
โทรศัพท์ works the same way at its tail. Leave โท-ระ as the exception you were given, the one that keeps its th sound, and look at ศัพท์. Cross out the final ท, and พ becomes the final, sounded p. The syllable is dead, and ศ is high class, which gives you a low tone on sap with no length question to settle.
อินเทอร์เน็ต is the one that proves the mark is not a full stop. The mark sits in the middle of the word, over ร in เทอร์. Delete that ร and the syllable is left open and live, with a mid tone, and then the word simply continues. เน็ต has no mark at all, so you read it plainly, and it lands dead and high.
So when one of these shows up this week, on a calendar as วันอาทิตย์, on a phone sign as โทรศัพท์, or by the wifi as อินเทอร์เน็ต, name the syllables first, find which one the mark closes, and read past it. I will be curious whether ทิตย์ tempts you toward a falling tone, because that slip would tell us the length check is the part to keep paired.
