connection / association
'Verbindung' and 'Kombination' can both express that several things come together. 'Kombination' puts more emphasis on the arrangement: different things are used together in such a way that they form a whole. 'Verbindung' is more general and often appears in the fixed phrase 'in Verbindung mit' (in connection with / together with), when something acts or is considered together with something else. With clothing, colors, ingredients, or methods, 'Kombination' often sounds more natural. In more formal contexts or when talking about effects, 'Verbindung' works well. Learners may confuse the words because a 'Kombination' is itself a kind of 'Verbindung'. In practical terms: 'Kombination' is the selection and mixture, while 'Verbindung' is the connection or interaction.
