it is important to note that there is no j street in any quadrant. the reason for this is that, until the mid-19th century, the letters "i" and "j" were indistinguishable when written. following that same idea, "i" street is often written as "eye" street, to distinguish it from the letter "l" and the numeral "1", and "q" street is often written "que", "cue", or "queue". urban legend had said that j street was omitted deliberately by l'enfant due to a dispute with john jay, the first chief justice of the united states supreme court; however, this was later proven to be a myth. jay street ne runs through the deanwood neighborhood; it does not belong to the series of lettered streets. there are also no x, y, or z streets in any quadrant, and most or all of a and b streets are called by other names in the mall area.
