Two words diverged in a yellow wood

It is strangely satisfying to consider that this was once a redundancy:

at his warning,
Whether in sea or fire, in earth or air,
The extravagant and erring spirit hies
To his confine:
(Hamlet I.i)

Which, to be historically accurate, should be translated as the out-wandering and wandering spirit.

I would be erring extravagantly if I didn't flag this Sandys quote in the OED:

Now dispersed into ample lakes, and again recollecting his extrauagant waters.
