Linguistics

So, this came up recently....think back to about 1986 or so. Where my sister and I lived, the hot vernacular was spelled "Sike", however Eddie and my husband publicly shamed me and said that it was in fact "Psych." While I see their point, I never saw "Sike" as an intellectual term with a lot of deep meaning and just took it at face value. I mean, in all my notes that were folded into envelopes and pushed through locker vents, it was always spelled "Sike." How about you?
