To help with intuition, here are a few example word vectors that we might encounter:

"fruit": {food: 0.99, gender: -0.05, size: 0.2}

"king": {food: -0.9, gender: 0.92, size: 0.56}

Building off of what v1n337 stated, though, axis can easily be skewed and rotated such that they're still interpretable, just not obviously so.
