There are some cases in English where one can substitute in a word that normally has an opposite meaning, but instead produces the same meaning. For examples, consider the following meanings and uses:
To complete; to provide information requested by a form:
This is the time of year when millions of procrastinating Americans fill {in, out} an IRS Form 1040.
To complete:
We can use these azaelas to fill {in, out} that hole in the landscaping left by the utility workers.
(SE questions on that one can be found at least here, here, and here.)
To silence by disabling e.g. a circuit or machine:
Yes, Dr. Freud, I’m familiar with the model of brain function as spreading activation through neural circuits. That seems to be working fine in this patient, but every time activation spreads to the concept of sexuality, there’s an internal alarm that goes off screaming “shut those circuits {up, down}!”
Little to no probability of occurrence:
{Fat/slim} chance.
Is there a term for this, and what other good examples are out there?
