"tlhIch purwI' 'oHbe'."

qech 'oH <Star Trek>. qech mIllogh bIH <The Original Series>, <The Next Generation>, <Deep Space Nine>, latlhmey je. pImlaH mIlloghmey.

Trying to say:

"This is not a pipe.

Star Trek is an idea. TOS, TNG, DS9, etc. are representations of an idea. Representations can differ."

Especially not sure about <tlhIch purwI'> due to the ambiguity of that; it could be a smoking device or a person who smokes.

tlhIch purwI' smoke inhaler: the subject of pur inhales something. The English might be ambiguous; the Klingon is not. tlhIch purmeH jan device for inhaling smoke might be a pipe, but it might also be a cigarette or a bong.

Whenever you use a pronoun as a verb, any noun phrases that go on the right side of the pronoun must have -'e' attached to them.

qech 'oH Hov leng'e'. qech mIllogh bIH much wa'DIch'e', puq poH veb'e', logh Hop tengchaH Hut'e', latlhmey'e' je.

With the understanding that you're talking about these things being qech mIllogh visual depictions of an idea. mIllogh means a visual depiction, not an abstract representation (unless it's a visual one).
