Wekî (IPA) tê gotin

/ˈdɪðə/

Variant of didder, from Middle English dideren (“to tremble”). Compare Middle English bididren, bididdren (“to seduce, deceive”), from Old English bedidrian, bedyderian (“to deceive, trick”). Alternatively, perhaps with expressive voicing from *titeren, from Proto-Germanic *titrōną. If so a doublet of teeter and cognate with Old High German zittarōn (German zittern) and Old Norse titra (Faroese titra, Icelandic titra). Alternatively an unrelated reduplicative onomatopoeia.
