When I write a simple... I wrongfully get corrected. As if an simple is correct.
Wrongly corrected, the opposite of rightly. "Rightfully/wrongfully" mean "having (or not) the right to something", eg, "he took what was rightfully his".
"a" before the word "simple" is being corrected grammatically to "an simple"... No. I don't think so. Some tweaking of the coding I think is required here.
I'm becoming more impressed with the course!! Tks..
