v

n
A leafless parasitic plant with slender, twining, yellowish stems.
Etymology
The verb 'dodder' emerged in the early 17th century, likely as an alteration of the earlier English dialect verb 'dadder' or 'diddle,' meaning to tremble or shake. This connects it to a family of Germanic words expressing unsteady movement or trembling. The underlying sense is one of physical instability. The noun, referring to the parasitic plant, derives from the verb in the late 17th century, named for its slender, trembling stems that appear to shake or totter as they climb a host plant. Thus, both modern meanings are vividly linked to the core concept of shaky, feeble motion.
Analysis
The word 'dodder' is a simplex word of Germanic origin. Its form is not productively composed of separable modern English morphemes.
