"there are still a few administrative i's to dot and t's to cross" [closed]

To "dot the i's and cross the t's" is an idiom meaning to be very thorough and meticulous in details, to take care of everything that needs to be taken care of. The "i's and t's" are just examples of small things that need to be done to make them complete: an "i" without a dot or a "t" without a cross stroke wouldn't be much of a letter.

The Wiktionary entry on this particular idiom can be found here.

I believe it is a metaphor based upon cursive, where the continuous writing of all letters in each word does not allow for some components of each character to be written at the same time as the main body of the character.

When writing in cursive, a common procedure after finishing each word is to go back to the start of that word and add those missing components, such as the dot and cross sections of the i and t letters respectively. More experienced writers occasionally prefer to perform this procedure for larger sections of text, in order to reduce the slight speed impact of moving their hand back and forth.

Until this post-processing happens, the text is still mostly readable, but not really complete.
