"Na faswn, byth!"
Translation:No I would not, never!
March 4, 2016
Both erioed and byth mean 'ever' in positive sentences, and 'never' in negative ones.
- erioed is used with past tenses (the simple past tense, and past tenses using wedi are the ones covered on this course) except the imperfect.
- byth is used with other tenses including the imperfect and the conditional (on this course, many of these tenses are constructed using yn).
