the body's busiest spy, reading the world in ridges no two people share.
means The very end of a finger, especially the soft padded tip used for touching, feeling, and handling things.
from A plain compound of two old Germanic words: "finger," which traces back through Old English to a Proto-Germanic root shared with German and Dutch, and "tip," meaning the pointed or extreme end — a word that surfaced in Middle English, possibly from a Low German or Scandinavian source. Put them together and you simply name the end of the finger, no fancier than "treetop" or "fingernail."
