The spelling of the phrase "wert host" follows English phonetic rules. The first word, "wert," is pronounced /wərt/ and is the archaic second person singular past tense of "be." The second word, "host," is pronounced /hoʊst/ and refers to a person who receives or entertains guests. Despite the absence of a space between the words, they are two separate words with distinct meanings. While the spelling may seem unusual, it is simply a reflection of the English language's complex history and evolution over time.
