like this, thus
恁 centers on pointing to a manner or state: 'like this' or 'thus'. It expresses a way of being or doing, often with a sense of immediacy or demonstration.
恁 combines 任 (which may contribute a sound element) with 心 (heart/mind), suggesting a mental state or manner. The exact historical development is uncertain.
The top 任 looks like a person carrying a burden, and the bottom 心 is the heart. Imagine someone showing you exactly how they feel by pointing to their heart: 'like this, thus'.
For イン, picture an inn where the host gestures 'like this' to show you to your room: inn -> イン.
