This post contains additional grammar videos to help you revise for the language test. These should all be read in conjunction with Dovid Katz’s excellent Grammar of the Yiddish Language which is available here. The page umbers in brackets refer you to that work. It is essential you consult Katz who covers the issues in much more detail than I do here.
More videos will be added as they become available:
Nouns: Gender, articles and plurals (pages 56-62)
Adjectives: Understanding endings changes (81-85) updated!
Verbs: Forming the present tense (pages 126-130) updated!
Forming the past tense in Yiddish (including verbs with separable prefix) new!
