1903 March 17, Mark Twain, letter to Helen Keller:
It takes a thousand men to invent a telegraph, or a steam engine, or a phonograph, or a photograph, or a telephone or any other important thing — and the last man gets the credit and we forget the others. He added his little mite — that is all he did.
"Well," I says, "I cal'late a body could get used to Tophet if he stayed there long enough." She flared up; the least mite of a slam at Doctor Wool was enough to set her going.
"Silas, now," Esther Whitley had said, "would be a good one for you, Hannah. He's a mite on the old side, but he's steady, an' he's been wed before. He knows the ways of a woman better'n some."

Those trousers are a mite too big, but you'll soon grow into them.
(colloquial,often used affectionately) A small or naughty person, or one people take pity on; rascal.
1971, Gwen White, Antique Toys And Their Background, page 35:
Today's children at Christmas-time take a cast-off toy to the Toy Service held in many churches, and it is a pretty sight to watch those tiny mites clutching their toys and parting from them.j

“Tom told me that, but twasn't your fault, the little mite just couldn't wait to be born that's all.” A small smile played on Leah's lips.
