terminate

[bbeeton]

Bring to an end, which can be either a simple statement of fact (use a period to terminate a sentence) or something much more emotional (he was terminated (from his job) today). Or, with an extra syllable, carried to an extreme: exterminate. There are related adjectives in the family: determinate, indeterminate, conterminate, and interminable. I'll end this now, before making everyone suffer terminal boredom.

[Slava]

This reminds me of what not to remind those who are afraid of flying. Don't mention that the place you're flying from and to is called a 'terminal'.
