Nakshatra

What the tradition reads
A nakshatra is one of twenty seven lunar mansions, equal divisions of thirteen degrees and twenty minutes each, into which the Vedic tradition divides the full 360 degree sidereal zodiac. Each nakshatra carries its own ruling planet, deity and symbol, and the tradition uses these to read a finer texture of character and circumstance than the sign alone provides, particularly for the Moon, whose nakshatra at birth, the janma nakshatra, fixes the starting mahadasha lord of the Vimshottari system, as Wikipedia's page on dasha describes: the first dasha runs to the lord of whichever nakshatra the Moon occupies at birth. Each nakshatra is further divided into four padas, or quarters, of three degrees twenty minutes apiece, giving one hundred and eight padas across the whole zodiac, nine of which fall within each of the twelve signs, a finer division the tradition uses alongside the whole nakshatra for the same kind of reading. The tradition treats the nakshatras as at least as fundamental to Vedic astrology as the twelve signs themselves, since the whole Vimshottari dasha system, one of the tradition's principal predictive tools, is built on nakshatra placement rather than on sign placement alone.
The story
Nakshatra is built from the Sanskrit root naks, to attain or to reach, and the suffix tra, marking a place, so the word names quite literally the place the Moon reaches each night, an image drawn directly from the practice that gave rise to the scheme: watching which star grouping the Moon stood against on each successive night of its passage. The system is attested in the earliest layers of Vedic literature, with the Atharvaveda listing twenty eight nakshatras against the twenty seven more commonly given in the Taittiriya Samhita and the Shatapatha Brahmana, a difference generally explained by an early lunar calendar that counted twenty eight nights of visibility across the roughly twenty seven and a quarter day sidereal month before settling on the rounder twenty seven division still used today.
