'Dazugeben' (to add) is a separable verb. The prefix 'dazu-' comes at the end in a main clause. In subordinate clauses, the verb stays together.
Gib jetzt das Mehl dazu.
Add the flour now.
You will find this verb especially often in cooking instructions and recipes. There it describes the step of adding another ingredient to a mixture.
Braten Sie die Zwiebeln an und geben Sie dann die Paprika dazu.
Sauté the onions and then add the bell peppers.
Besides the literal meaning in cooking, you can also 'dazugeben' (contribute/add) something to a shared cause, for example money for a gift or an opinion in a discussion.
Für die Party hat jeder etwas Geld für die Getränke dazugegeben.
For the party, everyone contributed some money for the drinks.
The colloquial idiom 'seinen Senf dazugeben' (to put in one's two cents) means to express one's opinion without being asked. It often has a slightly negative or ironic connotation.
Egal was wir besprechen, er muss immer seinen Senf dazugeben.
No matter what we discuss, he always has to put in his two cents.
to contribute
'beitragen' and 'dazugeben' can both mean that someone adds something to something shared. 'dazugeben' sounds more concrete and often more colloquial. You give something toward something, for example money to a collection or an opinion in a discussion. 'beitragen' is more general and can also refer to a larger or less visible part that leads to a goal or result. Learners may confuse the words when someone is doing their part. When something is really being added, especially money or a brief thought, 'dazugeben' fits. When the contribution leads to a result, 'beitragen' often sounds more natural.
