I remember watchingecce being given at the National Spelling Bee finals on ESPN several years back, and this (used to call attention to one persecuted unjustly) was how the pronouncer defined it.Khemehekis (talk)11:08, 19 December 2018 (UTC)Reply
The definition is quite plausible, because most English speakers' familiarity with the word (at least at one time) likely comes from the famous phrase in the Vulgate, "Ecce homo", uttered by Pontius Pilate in reference to Jesus after his scourging.Andrew Sheedy (talk)18:51, 19 December 2018 (UTC)Reply
I found three cites that use it in English (as opposed to mentions or uses in Latin) -- they are on the citations page. In one case, it was italicized, which could be taken to mean that the author considered it Latin. In all three cases, the meaning seemed more to echo the Latin definition ("Behold") rather than the given definition.Kiwima (talk)21:27, 19 December 2018 (UTC)Reply
