Which coordinating conjunction is used for explaining reasons?

The coordinating conjunction 'denn' is used to provide a reason or explanation for the action or state described in the main clause. In this case, the desire to buy milk is explained by the fact that there is no milk at home. Note - 'weil' can also fill this role, but doesn't fit in this sentence grammatically as the verb would need to move to the end.

• Coordinating Conjunctions

The coordinating conjunction that is used to show a contrasting idea or correction is 'sondern', which means 'but/on the contrary'. 'Sondern' is used specifically after a negation to introduce an alternative or a contrasting statement, implying a correction or refinement of what was negated. It's similar to "but rather" or "but instead" in English.

• Coordinating Conjunctions

The coordinating conjunction that is used to show contrast is 'aber', which means 'but'. In this example "aber" introduces a contrasting statement to "Es regnet," showing an intention to act despite the rain.
