Shema Yisrael
Up until the mid-twentieth century, the use of the word "Adoshem" combining the first two syllables of "Adonai" with the last syllable of "Hashem" was quite common. It took a few centuries for the word to fall into almost complete disuse. Despite being obsolete in most circles, it is used occasionally in conversation in place of "Adonai" by Jews who do not wish to say "Adonai," but need to specify the substitution of that particular word. It is also used when quoting from the liturgy in a non-liturgical context, especially as a substitute in musical pieces where a replacement for "Adonai" must have the same number of syllables. For example, Shlomo Carlebach performed his prayer "Shema Yisrael" with the words "Shema Yisrael Adoshem Elokeinu Adoshem Eḥad" instead of "Shema Yisrael Adonai Eloheinu Adonai Eḥad."
