Morphology

taproot = tap + root (transparent) = tap + root

A standard compound of two common nouns used in botany; the meaning 'main/root that extends deeply' is directly expressed by the components.

Etymology

Taproot is formed from the words tap and root; think of tap like when you 'tap' a tree or a barrel to draw water or sap from deep inside, so a taproot is the deep main root that reaches down for water and gives the plant its strength.
