Conjugation of 'luire' in the passé simple

Question

I have checked the rule and your answer does not follow the rule. Therefore I checked conjugation tables for luire which support the notion that your answer is incorrect, and that the correct answer was not present. According to these conjugation tables Luire in the passé simple has these conjugations: je luisis tu luisis il luisit "Now the city would fall into the 3rd category 3rd person singular and so the correct answer is surely luisit - Ian

Answer

Bonjour Ian,
I reread the lesson and it certainly points out the following:
EXCEPTION with "luire": 
The verb luire (to glow/to glisten) and its derivatives (reluire...) accept 2 conjugations:
- the regular one:  je luisis, tu luisis, il luisit, nous luisîmes, vous luisîtes, ils luisirent
- and the irregular one: je luis, tu luis, il luit, nous luîmes, vous luîtes, ils luirent
However, I am not finding the question which includes a city using luire.  Perhaps you can copy the phrase and resubmit your question.
Bonne chance.

Answer

Voilà la phase: Cette nuit-là, la ville ________ de mille feux.That night, the city glowed with a thousand lights.(HINT: Conjugate "luire" (to glow) in Le Passé Simple)

Answer

I was unaware that there is an irregular conjugation of luire in the passé simple.  I thought that there was a typo so I left it blank.  I think both answers should have been available and one or both forms should have been accepted.
