Yeah but his original name really is unpronouceable because it would take literal days to spell out, if I remember correctly. So it’s not completely unrealistic for others to want a shorter version. Like when Taumata­whakatangihanga­koauau­o­tamatea­turi­pukaka­piki­maunga­horo­nuku­pokai­whenua­ki­tana­tahu gets shortened to Taumata Hill in english.
