I guess this question is more about English than Czech... ANother is the singular form (you have the "AN" there in front of it) whereas other should be plural. Since English does not have different forms of adjectives based on gender, both "another" and "other" can be translated into Czech to all three genders - the former into singular genders and the later to plural ones. Other -> jiní, jiné, jiná (pl M,F,N) and another -> jiný, jiná, jiné (sg M,F,N).
Thanks for your input. A Czech friend just told me that the equivalent would be "jiný" (or other gender endings) for "other" and "druhý" for another. Of course, context is a factor too, and we don't have context when it's just two words like "jiná holka." PS Note that "other" in English is sg and "otherS" is pl.
You're welcome ... "druhý" means "second" and as it is in English, you can often use it instead of "another" ... or maybe rather instead of "the other" (maybe it's used more often than in English like that). For example: "This is one way and that is the other/second way". I'm not sure how far I should go in explaining English grammar... but trust me, "other" without the "the" or "an-" article in front of it should not be used in front of a countable singular noun. When you see a simple "other" with no article, there should be a plural or an uncountable noun after it... OtherS is used only when there is NO noun coming after (refering to something plural, but not stating it explicitly)... maybe you can check out some grammar website about this.
Little is not exactly synonymous with young here, they are not freely interchangeable. A young girl can also be 14 years old. A little girl is a very young girl, like 4.
Czech uses "mladá" and "malá" the same way, often also using a diminutive form of "holka" - "holčička" - with "malá" (or even by itself).
So, it's better to translate "mladá" as "young" and "malá" as "little".
This confuses me as well. According to WordReference, jiná is different or strange, and další means next, another.
Maybe, like hezká, it has to do with whether it modifies a person or an object?
That's really an English grammar question. The "an" in "another" works basically like the indefinite article "a"/"an". You can have either "another" or "the other" but not "the another", which is like using both articles in "the a girl". And like always with articles you omit the indefinite article in plural: "other girls" or "the other girls" but NOT "another girls".
