[the H is redundant other than for rhythm, although DARE suggests a link to IHS, the monogram for Jesus; note Quinion 5/8/00: ‘There have been various theories, but the one that seems most plausible is that it comes from the Greek monogram for Jesus, “IHS” or “IHC”. This is formed from the first two letters plus the last letter of His name in Greek (the letters iota, eta, and sigma; in the second instance, the C is a Byzantine Greek form of sigma). The H is actually the capital letter form of eta, but churchgoers who were unfamiliar with Greek took it to be a Latin H.’]
