The spelling of the word "guttier" may seem unusual, but it can be explained through the International Phonetic Alphabet (IPA). The first syllable, "gut," is pronounced with a short "u" sound, as in "cut." The second syllable, "-tier," is pronounced with a long "e" sound, as in "ear," followed by the "er" sound, as in "her." Thus, "guttier" is pronounced /ˈɡʌtiər/, with the stress on the first syllable. This word means "more like a gutter" and is commonly used in architectural and construction contexts.
