The spelling of the phrase "were vertical" can be explained using the International Phonetic Alphabet (IPA). "Were" is pronounced as /wər/, with a schwa sound for the "e". "Vertical" is pronounced as /ˈvɜrtɪkəl/, with the stress on the second syllable and the "er" sound represented by the schwa sound again. The spelling of both words follows English language conventions and is consistent with their phonetic sounds. Together, "were vertical" describes something that was in an upright position.
