Ein Paar Schule = the article "ein" refers to Schule, which is a masculine noun and not Paar, right? Otherwise it would be eine Paar Schule, because Paar is a feminine noun. Can I consider this a rule?
how to decide the gender of each noun? in my language it depends from the ending of the word. masculin, feminine, neutral? are there any rules or should I just remember each word?
