What is that little dot above a lowercase "i" called?

Answer 1

Tittle - same for lowercase j.

Wikipedia reference - "The tittle first appeared in Latin manuscripts in the 11th century, to distinguish the letter i from strokes of nearby letters. Although originally a larger mark, it was reduced to a dot when Roman-style typefaces were introduced.
The only place a modern reader is apt to confront this word is during the introduction to the Antithesis of the Law in the Gospel of Matthew (5:18): "For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled" (NKJV). The quotation uses them as an example of extremely minor details. The phrase "jot and tittle" indicates that every small detail has received attention."

Answer 2

The dot is purely pronounced as superscript dot. It grow to be added to the letter i contained in the middle a at the same time as to tell apart the letter (in manuscripts) from adjacent vertical strokes in such letters as u, m, and n. J is a version type of i which emerged right now and consequently grew to grow to be a separate letter.
