(A proofreader's note regarding “disinterested” and “uninterested”)

“Uninterest,” the noun, is both shy and unhappy,

“Disinterest” more likely the star.

Though different in name, they mean naught but the same,

With the latter the favorite by far.

It's no wonder, then, that their adjectives jostle,

Confusing and causing misuse.

“Disinterested” matches “uninterested,” surely,

But carries more meanings to choose.

“Uninterested” only means “simply not interested,

Feelings or mind not engaged.”

“Disinterested” brings up “no longer enticed,”

Which is added to sense much alleged.

Most commonly, though, when “disinterested” features,

It tells of “impartial” and “fair.”

This usage as “free from an interest that's selfish” 

Will find in the other no peer.

“Disinterested folk were selectively chosen--

Impartial, they suited the job.

The sponsors did wish them uninterested also,

Incurious and blind as a knob.”

“The tired and clearly disinterested tenor 

Let every high note go adrift.

The listeners, all children, were so uninterested

Not even the sharpest were miffed.”
