What does didder mean?
Didder means to tremble or shake, especially with cold, fear, or frailty. It is closely related to 'dither', and historically the two words were variants of one another: both descend from Middle English roots describing rapid, unsteady movement. Over time their paths diverged, with 'dither' drifting toward mental hesitation while 'didder' retained its purely physical sense of shivering or quivering. Today didder is uncommon and carries a distinctly literary or dialectal flavor; writers reach for it when they want an evocative alternative to more ordinary verbs like 'tremble' or 'shiver', often to suggest age, weakness, or vulnerability — an old man's hands that didder around a cup, or leaves that didder in the wind. It may also be used as a noun for a state of trembling. Though rare, it is a legitimate English word recorded by major dictionaries, and its kinship with 'dither' makes it a small but interesting piece of the language's history.
To tremble or shake, especially with cold, fear, or weakness; to quiver rapidly.

Didder and dither began as the same trembling word — one kept shaking, and the other started hesitating.

Etymology of didder
Didder comes from Middle English 'didren' (also appearing in forms like 'dideren'), a frequentative verb meaning to tremble or quake, likely of imitative or expressive origin like many words for shaking. It is intimately connected with 'dither', which arose as a variant of the same word family; the two existed side by side for centuries before their meanings diverged. Cognate or related expressive forms appear in other Germanic languages, such as Dutch 'didderen', reflecting a common pattern of reduplicative syllables used to evoke trembling motion. The word has been recorded in English dictionaries since at least the early modern period, though it has always remained relatively rare.
How didder is actually used
Didder is a rare, somewhat archaic or dialectal word today, found mainly in literary or regional use. It carries a slightly old-fashioned, evocative tone compared with everyday words like 'shake' or 'shiver'. It can also function as a noun denoting a trembling state.
