Usage tips
Separable verb
'Ausdenken' (to come up with) is a separable verb. The prefix 'aus-' goes to the end in main clauses, but stays connected to the verb in subordinate clauses. In the infinitive with 'zu', 'zu' stands between the prefix and the verb.
EXAMPLE
Ich denke mir schnell eine Ausrede aus.
I'll quickly come up with an excuse.
Reflexive dative construction
This verb is almost always used reflexively with a dative pronoun and an accusative object. The structure is: person (nominative) + denkt sich (dative pronoun) + something (accusative) + aus.
EXAMPLE
Du denkst dir immer die besten Geschenke aus.
You always come up with the best gifts.
Typical collocations
You can come up with both creative and positive things as well as negative things. Typical nouns are 'eine Geschichte' (a story), 'ein Plan' (a plan), 'ein Spiel' (a game), but also 'eine Ausrede' (an excuse) or 'eine Lüge' (a lie).
EXAMPLE
Die Kinder haben sich eine ganze Fantasiewelt ausgedacht.
The children came up with an entire fantasy world.

ausdenken vs entwickeln
to develop
'entwickeln' and 'sich etwas ausdenken' can both mean that a new idea comes into being. 'entwickeln' sounds more planned and often longer-term: you work out an idea, a product, or a solution step by step. 'sich etwas ausdenken' puts more emphasis on thinking and inventing something in your head. It fits well with stories, plans, ideas, or even excuses. When an initial idea later becomes something precise and usable, you are more likely to say 'entwickeln'. When someone comes up with an idea spontaneously or creatively, 'sich ausdenken' fits better.
