@roger,
Please, no apologies for spelling (hexing another matter ) or spilling or spalling...pretty sure spalling is a word and not just the anti s'wonderful. I'll look it up in a bit. I'm a retired English teacher who has never been very good at spelling. When I corrected students'work I always kept a dictionary close by, and if I was at home would call out to my husband or my son, both excellent spellers, for help. I'd tell my students to look at what I wrote on the board and if they thought something was misspelled, check a dictionary and let me know. Another issue when writing on the board, or elsewhere, I use/d a combination print and cursive. A pinch, twinge of arthritis did not improve legibility. Whenever I use the computer I give thanks for "backspace" and shudder at the memory of WhiteOut, liquid or those tiny strips that you positioned shiny side out, matte/powdery side in against what was to be erased.
Went to Dictionary.com and found spall. Noun, a chip or splinter, Verb, to chip or splinter. Love to learn something new, or relearn something forgotten.
