The term DOT ABOVE THE I is a diacritic mark used in many languages, including Spanish and French. It is also known as a TITTLE, which is the six-letter answer to the crossword puzzle. The dot above the i is used to differentiate between two words that are spelled similarly but have different meanings. For example, in Spanish, the word 'si' can mean either 'YES' or 'IF, ' and the dot above the i is used to distinguish between the two. In French, the dot above the i is used to indicate a nasalized vowel sound.
