NADIRA (نادرة).  A feminine form of Arabic Nadir (q.v.), meaning "rare, singular, uncommon."

'Twas thence Nadira came, and still
Her memory kept that lofty hill;
The vale below, her place of birth,
That one charm'd spot, her native earth.
Still haunted by that early love,
Which youth can feel, and youth alone;
An eager, ready, tenderness,
To all its after-life unknown... (The Poetical Works of Miss Landon, 1841)
