Reflexive + direct object (double pronouns)

What's your question. 

Hi J, It's because the subject of the verb is 'Je'. So in English, it's 'I brush' and in French 'Je (me) brosse. The verb agrees with the subject and not the object (teeth). And brosser is regular, so Je brosse, etc.

Merci bien, I had forgotten the reflex and was into the preceding direct object.. so easy to get lost in the maze.

Hi i too teplied je les couvres instead of je les couvre... 

so if ive understood corectly it would be tu les couvres 

elles les couvrent ?? 

Subject rather object

Hi Noeleen,  you have, I believe, just upped the confusion stakes another level.  It is only the past participle of the verb that agrees with the preceeding direct object and then only when the auxiliary verb is avoir.  The être verbs in the passé composé agree with the subject.  In the present tense verb construction there is no agreement with the object so yes je les couvre, tu les couvres.  I think this is right but you definitely had me going for a minute.

And of course I too had forgoten that.  Witness my original question.  Oh dear!

Bonjour Sukanya, Reflexive verbs require a reflexive pronoun: Je me lève, Tu te lèves, etc. In the case of nous and vous, the reflexive pronoun is the same as the subject pronoun: Nous nous levons, Vous vous levez. The lesson you've responded to is fairly advanced; please take a look at this more basic one and let me know if you still have questions: https://progress.lawlessfrench.com/revision/glossary/pronoun-type/pronoms-reflechis-reflexive-pronouns
