The phrase "wert bottom of" is spelled with the letter "e" even though the word sounds like it should be spelled with an "o." This is because it is a contraction of "wert thou at the bottom of" and "thou" is an archaic form of "you" which was commonly spelled with an "e." In IPA phonetic transcription, the word would be /wɜːrt ˈbɒtəm ɒv/, with the emphasized syllable being pronounced like "wurt."
