Do you mean clean as in "not dirty"? Or as in "not on drugs"?
"not dirty"
We are clean = We zijn schoon
"not on drugs"
We are clean = we zijn nuchter (nuchter = sober)
But I would recommend saying "we hebben geen drugs gebruikt" ("we haven't used any drugs" or "we are not on drugs right now".)
I had is in Dutch ik had.
'star' is in Dutch 'ster'
"Defense" in Dutch is "defensie".
In Dutch, six = zes.
It is the same way as you spell it in English.
groot is the word for great in Dutch. It is translation from English to Dutch.
"Dakota" is spelled the same in Dutch as it is in English.
The same, you don't spell names different in dutch.
'Paard'.
