Disinterested vs. Uninterested

Disinterested means impartial; free of bias and self-interest; without a stake in; not influenced by considerations of personal advantage.

• Sam as a banker offered his disinterested advise to his client.
• A judge is always under an obligation to give a disinterested judgement.

Uninterested means not interested; indifferent.

• Since she discovered skating, she is uninterested in her schoolwork.
• Sarah was always uninterested in the gossips involving the famous stars.

Usage Note: In traditional english usage, disinterested cannot be used in the same way as uninterested. But despite critical disapproval, disinterested has come to be widely used by many educated writers to mean uninterested. Despite its resuscitation, this usage is widely considered an error.

Imply vs. Infer

Imply means to suggest; to indicate indirectly; to involve by logical necessity; to hint at.

When a speaker or sentence implies something, it means that it is conveyed or suggested without being stated outright: When the minister said that he would not rule out a tax increase, he implied (not inferred) that some taxes might be raised.

• Shania did not actually say that there was going to be a delay but she implied it
• The size of Sam's house implies he is doing all right.

Infer is sometimes confused with imply. 

Infer means to deduce; to figure out; to conclude from evidence or premises; surmise; to lead to as a consequence; to reason from circumstance.

Inference is the activity performed by a reader or a interpreter in drawing conclusions that are not explicit in what is said: When the minister said that he would not rule out a tax increase, we inferred that he had been consulting with his new advisers, since his old advisers were in favour of tax reductions.

• I inferred from Sam's terse reply that I had offended him.
• From the annual financial reports economists inferred the company was about to go bankrupt.
