Part of speech: Verb
Definition: Cyflawni gweithred y bwriedir iddi ddychryn person, yn enwedig er mwyn ei gymell i weithredu mewn ffordd benodol. Gall y weithred fod yn eiriol neu'n gorfforol. Mae'n drosedd benodol, neu'n gallu bod yn rhan o droseddau penodol, o dan ddeddfwriaeth sy'n ymwneud ag aflonyddu, cyfiawnder, y drefn gyhoeddus ac etholiadau.
Context: Nid yw etholiad yn agored i gael ei ddirymu ac eithrio o dan yr erthygl hon oherwydd llygredigaeth gyffredinol, llwgrwobrwyo, tretio neu fygylu.
Notes: Gan gynnwys yng nghyd-destun etholiadau. Daw'r testun cyd-destunol o Orchymyn Senedd Cymru (Cynrychiolaeth y Bobl) 2025. Sylwer ar ystyr cyfreithiol penodol y term yn y cyd-destun hwn, lle mae angen gallu gwahaniaethu rhwng 'threaten' ac 'intimidate'. Mewn cyd-destunau annhechnegol ac mewn ystyron cyffredinol, gellir defnyddio 'bygythiad' am 'intimidation'.
