I've learned the word 'spine-tingling' in an Oxford book. While when I look up that word in the Websters dictionary,there only comes out 'spine-chilling'. I perceived them as synonyms but no evidence suggests that. So what's the difference between them and what are their usage?
There is a picture in today's Otago Daily Times of a man running whilst he is ablaze from an explosion, and the caption reads, " The spine-tingling image of a man running while engulfed in flames ", etc.. This, to me, should be described as ' spine-chilling' rather than tingling, because of the horror and life threatening aspect. Spine tingling is a different experience altogether, I think anyway.
