u
Casual written second-person
U is the twenty-first letter of the English alphabet.
In casual writing, especially texting and online communication, u substitutes for the word "you": u coming tonight? , see u later.
This shorthand is informal and typically avoided in professional contexts. (Capitalized U has additional meanings.)
