One of the songs we sang last night in the ukulele group was Abba’s Super Trouper. One member of the group wondered whether trouper was spelled correctly, thinking that it should be trooper.

We discovered that they are in fact two different words:

Trouper = a member of a theatrical company (a troupe); a veteran performer; a reliable, hard-working and unselfish performer [Source].

Trooper = a soldier of private rank; a cavalry horse; charger; one who endures adversity or hardship with an attitude of stoicism and persistence [Source].

Both words come from the French word troupe (troop), from the Old French trope (band, company, troop), from the Frankish *thorp (assembly, gathering), from Proto-Germanic *þurpą (village, land, estate), from the Proto-Germanic *treb- (dwelling, settlement) [source].

However, the word trouper in the song has nothing to do with the above words – “Super Trouper” actually refers to spotlights used in stadium concerts [source]. So now the first line, “Super Trouper beams are gonna blind me”, makes sense.

This is a version of Super Trouper in Swedish:
