Word Origin and History for tap-root
Online Etymology Dictionary, © 2010 Douglas Harper
- The main root in gymnosperms, eudicotyledons, and magnoliids, usually stouter than the lateral roots and growing straight downward from the stem. The taproot develops from the primary root. The taproot and its lateral roots penetrate deeper into the soil than the fibrous roots characteristic of monocotyledons. Compare fibrous root.
