The word "IL B L" may seem like a jumble of letters, but in fact, it is a common abbreviation for the phrase "I'll be all." When pronounced, the first two letters "IL" are pronounced as /aɪl/, which is the same sound as "aisle" or "file." The next letter "B" is pronounced as /bi/, which is the same sound as "bee" or "beet." Finally, the last two letters "L" are pronounced as /ɔl/, which is the same sound as "all" or "call." So, when spoken aloud, "IL B L" sounds like "I'll be all."
