Triple negative

From Teflpedia

A triple negative is a clause that has three elements of negation.

These may be found in some non-standard dialects of English, for example:

"I didn't say nothing to nobody".

This sentence would usually be interpreted as having negative concord. For example, it could have been spoken by criminal A denying to criminal B that he had spoken about crimes committed by criminal B.

According to the standard English logical interpretation of double negatives being positive (since two negatives make a positive), a triple negative would also seem to be negative (since three negatives make a negative).

In standard dialects, these may be occasionally found, usually as at attempt at obfuscation.
