A question concerning existence using all five two letter words in the English language that begin with the letter 'i'.
Each word is a different part of speech: noun, pronoun, conjunction, verb, and preposition.
One example where all the words are used sequentially, but not in the same sentence -- and id is not really a word in this case.
Here's another instance of all the words being used in a single clause -- once again id is not really a word.
The common phrase "if it is in" uses 4 out of 5 of the two-letter 'i' words.
