mahlen vs stoßen
to push / bump / come across
'stoßen' and 'mahlen' can both mean that something hard is made smaller, for example into powder. The difference lies in the type of movement and the tool. 'stoßen' is used when you crush something in a mortar with forceful pounding movements. 'mahlen' is used when a device or mill makes something fine by rubbing or rotating, especially coffee or grain. Learners may confuse the words because the result is often a fine powder. Remember: you crush spices in a mortar with 'stoßen'; you grind coffee or grain in a mill with 'mahlen'.
