A nearling is a positive word for something new that you did with the right intentions, which has not (yet) led to the right result.
The reasons for nearlings not to succeed can be diverse, the circumstances have changed; a better option has been chosen; you made an error; faith decided differently; there suddenly were other priorities, etc.
Until this moment there was no right English word for this phenomenum. There is the word 'failure', yet that sounded negative. You only recognize a nearling when you look back. You can always learn from a nearling. The nearling fills a gap in the international innovation language.
