Usage tips
Separable verb
'Klarmachen' (to make clear / to sort out) is a separable verb. The prefix 'klar-' comes at the end in a main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
EXAMPLE
Ich mache dir die Regeln klar.
I make the rules clear to you.
Word structure
The verb is made up of the adjective 'klar' (clear) and the verb 'machen' (to make). The literal meaning 'etwas klar machen' (to make something clear) helps you understand the figurative meaning 'etwas verständlich machen' (to make something understandable).
EXAMPLE
Kannst du mir bitte klarmachen, was du genau meinst?
Can you please make clear to me what exactly you mean?
Sentence structure with dative
In the meaning 'erklären' (to explain), the verb almost always needs a person in the dative, to whom something is made clear, and a thing in the accusative.
EXAMPLE
Der Polizist machte dem Fahrer klar, dass er einen Fehler gemacht hatte.
The police officer made it clear to the driver that he had made a mistake.
Register: colloquial

Reflexive use
In the meaning 'erkennen' (to recognize) or 'einsehen' (to understand/admit), the verb is used reflexively with 'sich' in the dative: 'sich (dative) etwas (accusative) klarmachen' (to make oneself aware of something / to realize something).
EXAMPLE
Du musst dir klarmachen, dass diese Chance nicht wiederkommt.
You have to realize that this chance will not come again.

klarmachen vs erklären
to explain / declare
'erklären' and 'klarmachen' can both mean making something understandable to someone. 'erklären' is neutral and fits in almost all situations, for example at school, at work, or in everyday life. 'jemandem etwas klarmachen' sounds a bit stronger and more personal. It often means saying something very clearly so that the other person really understands or accepts it. In factual texts, 'erklären' is usually more natural; in conversations, 'klarmachen' often sounds more direct.
