The word "bleich" is often misspelled due to its uncommon spelling. The correct IPA phonetic transcription for this word is /blaɪx/. The letter combination "ei" in German often represents the sound /aɪ/, which is similar to the English "eye" sound. The final letter "ch" represents the sound /x/ which can be pronounced like the "ch" in the Scottish word "loch". Therefore, the spelling of "bleich" should be pronounced like "bly-kh" in English.
The word "bleich" is a German term that translates to "bleach" in English. The etymology of "bleich" can be traced back to the Middle High German word "bleich" and the Old High German word "bleih", both of which also mean "pale" or "colorless". These Germanic roots are thought to have derived from the Proto-Germanic word "*blaikaz", meaning "light-colored" or "shining". Over time, the term "bleich" came to specifically denote the lightening or whitening of fabrics or substances through the process of bleaching, and it eventually acquired the more specific meaning of removing color from hair or making it lighter.
