I (Cyrillic): Meaning (information, definition, explanation, facts)

I (И, и) is the tenth letter of the Cyrillic alphabet. It looks like a backwards N and is pronounced like the I in the English word "machine". Note that although it corresponds to "I", it actually arose from the Greek letter eta, which looks exactly like an H.

With a short sign on in, it forms a new letter, Short I, which can be used to form diphthongs like the following:

• ai in aisle
• ei in vein
• oi in oil
• ui
