grekla lujvo

x1=p1=k1 passes through portal/generically exits or enters via portal (entrance/exit) x2=p2 to destination side x3=p3=k2 from origin side x4=p4=k3 via route x5=k4 using means/vehicle x6=k5.

x5, in its fullest possible description, must include x2. This word emphasises movement or transportation, usually unidirectional for any given x1 at any given time (not simultaneously bidirectional nor back-and-forth). It is meant to be a generic form of "nerkla" and "barkla", and is intended to approximate/analogize/extend their veljvo compositions. Aside from the aforementioned emphasis and intent, as well as the terbri, it is quite similar to "pagre" itself, although their might be further slight connotational differences (such as the means of passage through the barrier and the type of barrier involved, whether being able to remain on both sides of the barrier statically is within scope of definition (it might be for "pagre" but is not for this word, at least to any significant extent), etc.). x2 is an exit or entrance when generic terminology is desired; a generic word for a portal or doorway (see: "vorme") technically is always equivalent, so long as the portal is open and functional, but we often conceptualize exits and entrances (whether unidirectional or bidirectional according to their designs) as being to or from the overall structure (such as a house or vehicle) and not merely internal to it (such as a bedroom or bathroom doorway in a house), and this word is intended to capture this implication more explicitly.
