adjectives with the 'soft' ending -ní do not vary in any of the genders or number in the nominative
It is "jinE devcE" but "poslednI devcE". Is there any rules for endings of nouns and adjectives? Like there are in Russian, e.g.: последняЯ девочкА (Я being just the soft version of A), другаЯ девочкА. So the ending of the adjective corresponds always to the gender ending of the noun in nominativ. Thank you!
There are 2 groups of adjectives in czech, "jiný/jiná/jiné" is an adjective with the "hard" ending,
while "poslední" is an adjective with the soft ending "-ní" and these do not vary in any of the genders.
When do you use devce instead of holka? (Sorry, phone keyboard doesn't have most of the Czech characters)
Děvče is much more formal and nice to say, holka is just plain and general. Same applies to "kluk" (informal) and "chlapec" (formal) for a boy.
I believe that makes sense in terms of Czech grammar, but logically, isn't there always just one last girl? Wouldn't another be a penultimate or second-to-last girl?
Just the way the language works, I'm afraid. Something to get used to... but maybe one of the CZ natives can provide a better explanation!
