Linguistically it is called 'sequential voicing,' which is 'rendaku' in Japanese. There are a number of theories to generalize the rules, but none of them is really successful:/ It would be better to simply memorize it. I am sorry. I know my answer does not really help you, but there are not many irregular forms, so you can do it:)

El doctor dice "Se acabaron los monitos saltando en la cama."

In this context, 'つく' will mean 'to be attached.' What he meant was that there are many small machines or parts attached to a big one. I hope this helps you to understand the video.

The more you read books, the better you understand kanjis. Depending on your level of Japanese, I can suggest you some readings. Please let me know if you are interested in:)

あまり間違いはありませんが、少しだけ訂正しました。

質問があれば聞いてください。

電話をかける means simply an action to call someone on a phone, but 電話をいれる means an action to call someone in order to notify some information. The second one tends to be used more in a polite way. I hope this helps you to understand better.

This is a great question, and I am sure many Japanese learners are confused. Here is my opinion. い adjectives are basic structures of adjectives in Japanese. When you write them with kanjis and hiragana, い adjectives tend to have both kanjis and hiraganas, which the hiragana part is called okurigana but you do not have to memorize the term. If you know kun yomi and on yomi, it is more easy to explain. The kanjis used in い adjectives usually have kun yomi. And grammatically, い parts can be conjugated. For example, the negation of 美しい(utsukusii, beautiful) will be 美しくない. On the other hand, the structure of な adjectives are different. Most of な adjectives can function as nouns without な. For example, 綺麗(kirei, beautiful)な, 素敵(suteki, great)な and 巨大(kyodai, enormous)な can function as nouns without な. 綺麗 is a noun that expresses a beautiful condition. 素敵 and 巨大 are same as this. They are nouns to illustrate certain conditions. If an adjective word can stand by itself without な part, it is a な adjective. Except な parts, な adjectives cannot be conjugated. The word きれい(kirei) ends with い, but this is an example of a な adjective. The negation of this word will be きれいではない. If I apply the conjugation of い adjective to きれい, it is going to be きれくない; however this is grammatically incorrect. I hope this explanation helps you.
