I understand the use of demonstrative adjectives as well as their declensions. What confuses the heck out of me, though, is the addition of -hle and the "this and that" constructions. 1) If I'm pointing out something within sight, do I add -hle to any of the declensions? For example, would it be: Mam tuhle tuzku. Rezomim tehle knize. 2) How do I use the ten a onen construction with the declensions? I understand that You would say something like "Potrebuju ten a onen." What would it be for other declensions, or is it only used with masculine nominative?
I guess you mean demonstrative pronouns, not adjectives. Ad 1. You understand it well, however the suffix -hle is colloquial; standard Czech uses the suffix -to as an intensifier. E.g. Mám tuto tužku. Rozumím této knize. Ad 2. Sure there are other genders and their declensions. Here they are: Masculine pronouns Nominative: ten a onen (sg.) - ti a oni (pl.) Genitive: toho a onoho - těch a oněch Dative: tomu a onomu - těm a oněm Accusative: toho a onoho - ty a ony Vocative: -- Local: o tom a onom - o těch a oněch Instrumental: s tím a oním - s těmi a oněmi Feminine pronouns Nominative: ta a ona(sg.) - ty a ony(pl.)
