telos

This word marks the finish line of a process, but Greek lets one word cover what English splits into several. It can be the moment something stops (the end of an age, the end of a life), the result something finally comes to (the outcome, whether good or ruinous), or the goal it was always heading for (the purpose that completes it). These are not separate ideas so much as three angles on one thing: the place where a movement is done.

Because of this range, translators have to choose a different English word almost verse by verse, and the choice can carry real weight. When Paul writes that Christ is the end of the law, the same word can mean the law has stopped or that the law has reached the goal it was pointing toward all along, and readers hear very different messages depending on which is meant.

The word also settled into a fixed phrase, best rendered to the end or to the last or fully, used for enduring all the way through hardship or loving someone completely. And in Revelation it becomes a name: God and Christ are the Beginning and the End, the one from whom everything starts and in whom everything arrives.

Alongside its main use, this word had a concrete everyday meaning in the marketplace: the toll, customs, or duty a person owed to the state. It is the kind of revenue collected on goods and travel, distinct from a head tax or tribute, and it is the money Jesus asks about when he speaks of the kings of the earth taking duties, and the obligation Paul has in mind when he tells believers to pay what they owe.

The link to the main meaning is faint but real: the underlying idea is something paid up or settled in full. For a modern reader, though, this is effectively a separate word, and context makes clear when money rather than an endpoint is meant.
