Questions & Answers about Не надо убеждать меня, эта чепуха даже хуже.
How does даже work in this sentence?
In this lesson, we are looking at emphatic particles. Даже means "even." Here, it emphasizes just how bad the situation is by pointing out an extreme degree: this nonsense isn't just bad, it is даже хуже (even worse).
Could I use же instead of даже here?
Not without changing the meaning. Даже хуже specifically means "even worse." If you used же (for example, эта чепуха же хуже), it would change the tone to a reminder or a slightly defensive statement, meaning "but this nonsense is worse, as you already know."
Why is the imperfective verb убеждать used here instead of the perfective убедить?
After the negative phrase не надо (no need to / you shouldn't), Russian almost always requires an imperfective verb. It conveys "there is no need to engage in the process of convincing me" or "don't even try." Using the perfective убедить here would sound unnatural.
What is the base form of хуже, and why doesn't it have a feminine ending to match чепуха?
Хуже is the comparative form ("worse") for both the adjective плохой (bad) and the adverb плохо (badly). A handy rule to remember is that simple comparative adjectives in Russian, like хуже, never change their ending to match the gender or number of the noun they describe.
