About how many irregular verbs are there in Slovak? Or how many irregularities in general (declensions and stuff like that)? This is something I really struggle with in language learning.
probably the easiest explanation regarding Irregular Verbs you can find under http://slovake.eu/en/learning/grammar/classes/classes/verbs/conjugation. The author of our Language Course and Grammar recommends to practise via Conjugation Exercises in the lessons, too.
More information regarding Declencion and Comparison of Adjectives and Adverbs you can find under http://slovake.eu/en/learning/grammar/classes/classes/adjectives/degrees. You can see that those irregular are similar to English .).
You can have a look at 5 Minutes Slovak under http://slovake.eu/en/learning/intro/pronunciation, too.
Don´t hesitate to write once again if we can help you...
Good luck with your Slovakian!
