IPA: /ˈdɒd.ər.ər/
KK: /ˈdɒd.ər.ər/
A person who moves in a slow, unsteady way, often due to age or weakness.
The old man was a dodderer, shuffling slowly down the street.
Dodderer originates from the Middle English 'dodder', which is of uncertain origin but is thought to be related to the Old English 'dodder', meaning to tremble or shake. The suffix '-er' indicates a person who performs an action. Therefore, a 'dodderer' refers to a person who shakes or trembles, often due to age or frailty.
Imagine someone who 'trembles' or 'shakes' — that's what a dodderer does, and the '-er' just means it's a person who does that.
