In poetry, a spondee --
from the Greek spondē, "libation" -- is a metrical foot consisting of two accented syllables. An example of a spondaic word is “hog-wild.”
Tennyson often made use of spondaic and pyrrhic
(a metrical foot consisting of two unaccented, short syllables) substitutions in his work:
Excerpt from In Memoriam by Alfred Lord Tennyson
Be near me when my light is low,
When the blood creeps and the nerves prick
And tingle; and the heart is sick,
And all the wheels of Being slow.
There are two spondees in this excerpt: "blood creeps," and "nerves prick."
Another example is Gerard Manley Hopkins’s “Pied Beauty” which is heavily spondaic:
Pied Beauty by Gerard Manley Hopkins
Glory be to God for dappled things –
For skies of couple-colour as a brinded cow;
For rose-moles all in stipple upon trout that swim;
Fresh-firecoal chestnut-falls; finches’ wings;
Landscape plotted and pieced – fold, fallow, and plough;
And áll trádes, their gear and tackle and trim.
All things counter, original, spare, strange;
Whatever is fickle, freckled (who knows how?)
With swift, slow; sweet, sour; adazzle, dim;
He fathers-forth whose beauty is past change:
Praise him.
