The fifth dozenal power of the ⚀lengthel, the ⚀pentqua·lengthel (abbreviated ⚀p↑lgℓ) is one dozen ⚀stadial·lengths, or one gross ⚀habital·lengths, or one galore ⚀ell·lengths, or one dozen galore ⚀hand·lengths, or one gross galore ⚀morsel·lengths. This is the distance traversed in 1 ⚀dwell (2 hours) when moving at 1 ⚀velocitel. In SI units, this comes out to exacty 2040.9408_d meters, just slightly over 2 kilometers. In USC units, this is exactly 6696_d|3ᘔ60_z feet.

This makes the ⚀pentqua·lengthel a good unit for travel distances, on the order of the mile. However, at more than a quarter larger than a statute mile (exactly 1.2681_d mi), calling the ⚀pentqua·lengthel some kind of "mile" would not be a good fit. (See here for a better mile analog.) The ⚀pentqua·lengthel is a new sort of unit that needs a new name coined for it.

About 2 kilometers appears to have been a threshold distance for a “long race” in ancient Greece. For instance, the dolichus (δόλιχος) event in the ancient Olympics has been described by one source as being a dozen stades long, or about 2.2_d kilometers (although most sources place it as being about a league, or 3 miles).

The ancient Greek word for “race-course” or “running track” is dromos (δρόμος). Several modern words incorporate it: palindrome, prodromal, hippodrome, velodrome, aerodrome, isodrome. In modern Greek dromos has evolved into a simpler and more generalized meaning of “road”, in just about every sense that “road” has in English. That includes not only a simple ordinary street, but also a “road to” someplace, and even the metaphorical sense of one's “road” through life. The ⚀pentqua·lengthel is certainly quite serviceable as a unit for measuring travel distances “on the road”. Consequently, Primel will adapt a Latinized form of this word, and colloquialize the ⚀pentqua·lengthel as the ⚀dromal·length.
