Unfortunately, your page doesn't mention this important phenomenon which is called беглая гласная 'a fleeting vowel.' The thing is like this: in some words, the stressed vowels o, e, and ё completely disappear, turn to null, when the form of the word changes and the stress moves onto another vowel. Your noun рот has its root stressed, but when we form the ...

Все дело в происхождении слова. В древнерусском «светлый» имело вид свѣтьлъ, а «смуглый» – смаглъ / смѧглъ. Исходя из современного состояния языка это объяснить сложно, проще запомнить, а лучше посмотреть в словарь. Подобных слов (внешне похожих, но с разной беглостью гласных) множество. Например: ветер – катер. В одном Е беглая (ветра), в другом нет (катера)...

The syllable structure is either CVC(ь), CVCVC(ь) or, as some user had put it above, CVCъ (historically). The one-syllable ...

1) The prohibitive form (Ru) with an infinitive (не + the infinitive) is more official and is used in a colloquial speech as a form of rude impersonal command only: Не играть с огнём. => Не играй с огнём. Не дразнить собаку. => Не дразни собаку. Basically, any verb of the -ать type changes into its singular imperative mode by the same algorythm: Не дела+...

No, this missing letter is just an exception. But there are exceptions for some plural nouns' endings like: Учи́тель - учителя́ (Род. падеж for singular - учи́теля) Дом - дома́ (Род. падеж for singular - до́ма) Вечер - вечера́ (Род. падеж for singular - ве́чера) Ветер - ветрá (Род. падеж for singular - ве́тра) As you ...

This extra vowel (mobile vowel) may appear in the grammatical cases when a noun has no ending. But you can't say for sure if it does. In your example this mobile vowel disappears in all cases except nominative, not just genitive. In my opinion, you should just memorize such words.
