ärahaakete

Could you clarify what you mean by "ärahaakete"? Is it a real Estonian term from a specific field (for example technology, biology, linguistics, history), a proper noun, or a coined/fictional concept? If you can provide the context or intended use, I can write a concise, neutral wiki-style article (under 300 words). If you’d like, I can also create a fictional encyclopedia entry for a made-up concept named "ärahaakete."
