I decided to try to construct a sentence similar to this, amusingly enough, on Sunday. Now I see this sentence again and wonder if I did it wrong: "Hver søndag jeg rene huset og vask klærne mitt."
How badly did I do? I wanted to say "do my laundry" for the second part, but we haven't gotten that word (laundry)....yet. (and, yes, that is my usual Sunday)
'rene' is an adjective and not a verb. To mean 'to clean', you could use the verb å rengjøre.
'vask' is a noun. The verb is å vaske
Remember to use the correct tense of each verb (in this case, the present tense) so 'å rengjøre' would be 'rengjør' and 'å vaske' would be 'vasker'
Because of the V2 Rule, remember to invert the subject and verb following a subordinate clause
So the sentence would be; Hver søndag, rengjør jeg huset og vasker klærne (*mitt)
*mitt can often be omitted if it's clear what you're talking about
