Tittle

And it is easier for heaven and earth to pass, than one tittle of the law to fail.

The foure pricks or tittles are these. The first is a full prick or period. The second is a comma or crooked tittle.

The words "jot" and "tittle" in this passage refer to diacritic marks, that is, dashes, dots, or commas added to a letter to accentuate the pronunciation.

(the page calls both "a superscript sign (hooklike)" and also a diacritical abbreviation of "er" (er) "tittles")

A tittle is more or less the same thing (the dot over an i, for instance), except that it can be traced back to Medieval Latin for a little mark over or under a letter, such as an accent ague or a cedilla. I don't know whether an umlaut is one or two tittles. Maybe it's a jot and a tittle side by side.

I am living fast to see the time when a book that misses its tide shall be neglected, as the moon by day, or like mackerel a week after the season. No man has more nicely observed our climate than the bookseller who bought the copy of this work; he knows to a tittle what subjects will best go off in a dry year, and which it is proper to expose foremost when the weather-glass is fallen to much rain.
