Good question, could also be the Finnish word "lahja" that translates to "gift"
Could also mean 'talent'.
Christoph, founder of the project here. I recently came across the Estonian meaning and jokingly used it as an explanation for the project name when I gave a presentation. However, the real story is that Lahja is the name of my daughter and I selfishly named this project after her :)
“Lah ja” in Hindi means “take away”
That sounds more Punjabi. It is "le ja" in Hindi.
It's also a pretty popular girl's name ;)
"lahja" in Arabic means dialect
Also means "weak" (in concentration) in Estonian though
