She just knew.
There was no vocabulary to describe it.
There was no precedence in recorded history known.
She knew it because her instinct told her so.
She knew it because she felt it and perceived it.
And yet could not describe it in words, because there was no vocabulary that could describe it.
Knowing is not always tangible.
Even if it cannot be put in words, described with an example, backed with evidence or tagged as a pattern, it is still a fact.
A fact that is not yet widely known, discovered or acknowledged by the world.
