I'd like to submit a question.
I am often in trouble when i have to indicate the relationship between objects (a ring, a purse, a door) and raw materials (gold, leather, wood).
something could be made of, out of, from, with .... is there a general rule, or we have to learn each case by heart?
We usually say made of when we are identifying the material used to make something. Most things seem to be made of plastic these days. What are your loudspeakers made of?
When we are thinking about the process of manufacture, out of is more often used.
They made all the furniture out of oak. (More natural than ... of oak.)
When a material is changed into a completely different form to make something, we often use make from. Paper is made from wood. (NOT Paper is made of wood.) My mother makes wine from blackberries.
To mention just one of the materials that something is made of, we use make with. 'The soup's good.' 'Yes, I make it with lots of garlic.'
