The correct spelling of the word "am pertinent" is "I am pertinent." The "I" in this phrase is pronounced as the personal pronoun, while "am" is pronounced as /æm/, with the /æ/ sound similar to the "a" in "cat". "Pertinent" is pronounced as /ˈpɜːtɪnənt/, with the stress on the second syllable and the long "e" sound in the third syllable. It means relevant or applicable to a particular matter, and is often used to describe something that is important or significant.
