In Wikipaedia or other related articles, ichthys is an acronym of Jesus Christ, God's Son, Saviour. Yes, it is, but it doesn't say ichthys is originated from this acronym. The history or etymology of this word is much older, this is a Greek word, from the offspring son of the ancient Sea goddess Atargatis, The word also meant "womb" and "dolphin" in some tongues, and representations of this appeared in the depiction of mermaids. excerpt from http://www.atheists.org/christianity/fish.html
Suppose even if we admit the word ichthys is an acronym of Jesus Christ, God's Son, Saviour...then why this word meant fish? I assume it is because this word originally meant fish.
