Compound sentences are described thus in TKD: "Two sentences may be joined together to form a longer compound sentence. Both sentences must be able to stand alone as properly formed sentences." Now see this from KGT: juDev 'ej Dujvam ra'wI' DagheS 'e' vItlhob I ask you to lead us as commander of this ship. In order for this canonical utterance to be legal according to TKD, juDev and Dujvam ra'wI' DagheS 'e' vItlhob must both be "properly formed sentences."

I'm going to take this one back. The formation is apparently [juDev 'ej Dujvam ra'wI' DagheS] 'e' vItlhob, which makes a compound sentence the first sentence of the SAO.

In compensation, I'll point out an example of using a purpose clause on an SAO: bIQapqu'meH tar DaSop 'e' DatIvnIS to really succeed, you must enjoy eating poison. This is bIQapqu'meH [tar DaSop 'e' DatIvnIS], not [bIQapqu'meH tar DaSop] 'e' DatIvnIS.
