The word "am alive" is spelled /æm əˈlaɪv/, using the International Phonetic Alphabet (IPA). The first sound /æ/ is pronounced like the "a" in "cat", while the second sound /m/ is the same as the regular letter "m". The third sound /ə/ is a schwa sound, like the "uh" in "above". The final sounds /ˈlaɪv/ are pronounced like "lie" (as in "to tell a lie") and "v" (as in "victory"). Together, they make the word "am alive".
The phrase "am alive" does not have an etymology by itself since it is a combination of the verb "am" and the adjective "alive". However, the word "alive" can be traced back to the Old English word "on life", which then evolved into "a lif" or "of life". Over time, it became "a live" in Middle English, merging into the compound word "alive" as we know it today.
