3. Read words from Latin/? /,such as machines, moustaches (French), machetes (Spanish) and pistachios (Italian).
4. read old English /D? /,such as sandwiches and spinach.
Ch pronunciation rules memory formula is as follows:
When ch is followed by the letter s, ch is pronounced k. Such as sechs, wachsen
However, it should be noted that when ch meets the highest suffix -ste in German, even if ch is followed by the letter S, it will not pronounce K, but keep the original pronunciation of ch. For example, the adjective flach and its superlative am flachsten are pronounced h.
There are no rules to follow, only practice makes perfect. Chemistry, personality, chorus and chorus send K, but the same group Chester, chat, choke and change send tch.
