English lexis can be really specific

Hiya ! 

Today I feel like writing a freak post that I have wanted to write for long. In fact, I don't know what to call it, so I tried to explain myself. Well, the English language has some generic terms that can refer to a lot of things. However, it also has specific words to distinguish. Yeah, it seems very difficult to understand, but let's try with examples : 

1. Bag : Bag in English in quite an open term that can refer to a wide range of different objects. Saying 'I lost my bag' may not be informative in English, given that the English have a lot of different types of bag :

   1a. Schoolbag

Well, as you can see, English is awesome since it can use one word to refer to similar but very different objects, but then it can be really specific by adding just one word before the noun. That's another English quirk that makes me love English even more  !
