Quite often used in poetry when it helps the rhythm and also to give an impression of "olde worlde" or foreign language.
Sing a song of sixpence.....four and twenty blackbirds baked in a pie
WHEN I was one-and-twenty
I heard a wise man say,
�Give crowns and pounds and guineas
But not your heart away;
Give pearls away and rubies
But keep your fancy free.�
But I was one-and-twenty,
No use to talk to me.
When I was one-and-twenty
I heard him say again,
�The heart out of the bosom
Was never given in vain;
�Tis paid with sighs a plenty
And sold for endless rue.�
And I am two-and-twenty,
And oh, �tis true, �tis true. AE Housman
I thought suddenly of Mother, scolding me when I was two-and-twenty, saying I must talk more when we went calling. Affinity - Sarah Waters (set in the late 1800s)
