Root Breakdown
Root-derivedrōdere (gnaw) + -ent (one that does) = 'a gnawing one.' This is the most literal word in the family: rodents are classified by exactly this trait — ever-growing teeth that force them to gnaw constantly. Hold onto a rat's teeth here and every other rod word's 'eating away' makes sense.
