Well, there are some general things I can teach you about Hebrew.
Unlike English, in Hebrew we have male and female for objects and other general words (for example: table is a male, couch is a female, emotion is a male, etc.)
It is expressed by some thing like How we use numbers (one couch is different than one table), and descriptions ((big couch is different than big table)
About plurals. Just like English language has the letters 's' for plurals, in Hebrew there are two different endigs for plurals, 'im' and 'ot'.
for example, knife = 'sakin' in Hebrew, and it is 'sakinim' in plural. table = 'shoolhan' in Hebrew, and it is 'shoolhanot' in plural.
