I won a school-wide spelling bee in elementary school. (There were fewer words back then!) I've always been a good speller. During my career, colleagues would call me on the inter-office phone and ask how to spell a word rather than look it up in the dictionary. (This was before Spellcheck came on the scene.)
As I've aged, it's easier for me to write (or type) the word than to simply try and visualize before spelling it. I'm not sure why this is true....Does anyone know?
