Hello, there are exceptions to this. Machine for instance has the 'ch' pronounced the French way, probably because (unlike mechanic) it was loaned from French.
Chaim is a Hebrew name.Also note some names:
Chaim Potok wrote a book called "The Chosen".
Chaim is pronounced hard, but deep in the throat; Chosen is pronounced soft.
Sorry, I'm lost.As in German, after non-front vowel you get velar /x/, as in 'loch' or 'sheugh', and after a front vowel you get palatal /c-cedilla/, as in 'teuchter' and 'dreich' - the rules of phonological conditioning.
BUT if you have Hebrew names with <ch> in the Old Testament, they would be /k/ rather than /x/ in English - as in Malachi, Zechariah, Baruch. EXCEPTION: Rachel.Chaim is a Hebrew name.
Here ch is the sound found in the Scottish pronunciation of loch /x/.
You will see Hebrew words transliterated in to English with h, or kh, or ch.
Hanukkah or Chanukkah
Hassidim or Chassidim or Khassidim
