Lacer verb is conjugated in female form and in reflexive form. Be careful, the past participle of compound tenses must agree with the subject.
Lacer 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
lacer 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 lace-t-elle pas ? »,
« ne laça-t-elle pas ? »,
« ne lacera-t-elle pas ? »,
« n'a-t-elle pas lacé ? »,
« n'aura-t-elle pas lacé ? ».
Always in interro-negative form, and always for sound reasons, an accent appears in first person present indicative tense when the verb ends with
« e ». An euphonious
« e » is replaced by
« é »:
« ne lacé-je pas ? ».
Finally, the interrogative form does not exist in subjunctive and imperative.
