“...“Sighted” or “Sited”..”
Sighted.
Without the “gh” the word “sited” refers to something “situated” or “located”. Like a “missile site” (base, platform, location).
“Sighted” refers to something viewed. “He sighted (viewed, spied, saw) the storm clouds in the distance...”
At least that’s always been my understanding of the difference.
Thank you for citing the difference!
