Elle trouve que Sam EST belle.
Elle trouve Sam ennuyeuse.
Does it work as a guide/rule that:
The presence of a conjugated verb after "trouve que" suggest both that
1) "trouve que" is being used in the sense of "think/find that...(clause)," and also
2) that "que" is necessary in the formation of such a sentence?
For comparison: "Elle trouve Sam est belle" would be grammatically incorrect.
