I had same problem. By the way it is nice to see someone using the forum two months ago or less
D L is a far way from accepting non-literal translations. My Latin teacher used to say..translate the idea, not the words. I guess it is unrealistic to expect a machine to match the fantastic power of human intelligence created by a Super Intelligent God.
I also tried sapling of tree.. it said its incorrect.. not sure why though
No, a "seedling" (mche) is not just a "seed" (mbegu). A seedling is a small plant that has germinated (come out and started to grow) from the seed. Before this happens, it's just a seed.
