-andre, -endre, -ondre, -erdre, -ordre conjugate like

d is only kept in the future and conditional.																												
																																																																																																		
Tordre is conjugated in interro-negative form. The interro-negative form being obtained by inversion of the subject, the placement of the negative adverb follow the same rules as in negative form, giving the following rules:
									
 - in interro-negative form, the adverb 
« ne » is always placed first if the subject is a pronoun.
									
 - in simple tenses, the adverbs (
« ne ...pas », 
« ne...plus », 
« ne...jamais », etc...) surround the verb 
tordre and the inverted subject pronoun.
									
 - in compound tenses or in passive voice, the negative adverbs surround the auxiliary and the inverted subject pronoun.
																		
																			
For sound reasons, like in interrogative form, an euphonious 
« t » is added to the pronoun of the third person: 
« il », 
« elle », 
« on », 
« ils », 
« elles » except when the verb ends with 
« t » or 
« d »: 
« ne tordra-t-il pas ? », 
« n'a-t-il pas tordu ? », 
« n'aura-t-il pas tordu ? ».
																											
Finally, the interrogative form does not exist in subjunctive and imperative.
