What is the meaning of phrase "ethereal minstrel" in "To a Skylark" by Wordsworth?

Perhaps the easiest way to define the phrase is to dissect
the phrase, define the words individually, and then place them back together within the
context of the poem.

First, ethereal refers to something so
perfect (delicate and light) that it seems too perfect to exist in the
world.

A minstrel is a medieval singer who would recite
poetry for entertainment.

Placed together, Wordsworth is
detailing a man whose person or voice seems too perfect to exist in the
world.

When placing the minstrel into the context of the
poem, one can conclude that the subject of the poem, a skylark, is admired to a point
above all others. Wordsworth exalts the bird in the poem. He does this by describing it
as something not of this world, something whose vision is limitless, something which can
withstand the flooding of the earth.

Always remember to
take the title of any work into consideration when trying to interpret any part of a
poem. The use of the phrase "ethereal minstrel" to describe the skylark places the bird
on a pedestal showing Wordsworth's honor and mystification of
it.
