The spelling of the phrase "am beside" can be confusing due to the silent "e" at the end of "beside." The correct pronunciation is /əm bɪˈsaɪd/. The symbol /ə/ represents the schwa sound, which is a neutral vowel sound often heard in unstressed syllables. The "i" in "beside" is pronounced as long "i," represented by /aɪ/. Remember that the "e" in "beside" is silent and does not affect the pronunciation of the word.
The phrase am beside is not a common expression or phrase in English. Am is a form of the verb to be in the first person singular present tense. Beside is a preposition meaning next to or alongside. However, if you are referring to the phrase beside myself, which is somewhat similar in structure, it means to be overwhelmed with an emotion or not in control of oneself. The etymology of beside myself comes from the Old English phrase be sidan me, which can be translated as by my side. It originally referred to someone standing close to a person who had lost their mental stability or self-control. Over time, the word myself replaced me, giving the modern phrase beside myself.
