      The origin of cursive script is one which intertwines technology and efficiency. We get the word “cursive” from the Latincurrere--    46     “to run.” It distinguishes writing in which the pen lifts from the page between words,   47    between eachindividual letter. Cursive developed out of typeface and print technologies, but more importantly it came from the need to writewell and to write quickly.But, cursive is fading. There is a debate over whether it has value in the classroom, but that debate extends further thansimply a matter of cursive--it's about writing itself. Many curricula are even favoring typing lessons    48   teachinghandwriting.
      The battle for cursive reaches deeper than questions of whether your letters “connect.” The pen--even morethan the text--might say something about us. Our handwriting might indicate our nationalities and educationalbackground,   49    Adrienne Bernhard's “What Your Handwriting Says About You.” Yet, Bernhard's article alsoindicates that the proliferation of typing--via emails, text messages, etc--might in fact undermine the distinctness ofour handwritings. The battle for cursive has always been a battle for the uniqueness of our handwriting andourselves, verses and the evolution of technology and push towards efficiency.
     Not too long ago, cursive--Spencerian script to be specific--“was the de facto standard writing style for businesscorrespondence before the widespread adoption of the typewriter.” With the development of the typewriter, cursive   50    outof business usage into the usage of personal correspondence; technology supplanted cursive's original purpose, but cursiveremained an act of self expression.
