repine [rɪˈpaɪn] v.i.
1.) To be discontented or low in spirits; complain or fret.
2.) To yearn after something: "Immigrants who repined for their homeland" (American Heritage Dictionary of the English Language).
Etymology: Middle English repinen, to be aggrieved : re- + pinen, to yearn.
"The night of sorrow now is turn'd to day:
Her two blue windows faintly she up-heaveth,
Like the fair sun, when in his fresh array
He cheers the morn, and all the earth relieveth:
And as the bright sun glorifies the sky,
So is her face illumin'd with her eye;
Whose beams upon his hairless face are fix'd,
As if from thence they borrow'd all their shine.
Were never four such lamps together mix'd,
Had not his clouded with his brows' repine;
But hers, which through the crystal tears gave
Shone like the moon in water seen by night" (Venus and Adonis, William Shakespeare, 1593).
Note: Shakespeare uses "repine" as a noun here.
