a way: the road you travel, and by extension the path your whole life takes
At its root this word names a road, the track worn by feet going somewhere. From that one picture the Bible draws nearly all its other uses. A road implies travel, so the word can mean the trip itself, its distance, or its direction. A road also implies a habit of going the same way, so it can mean the customary manner in which something is done.
The move that matters most is the step from a physical road to a life lived. Hebrew pictures a person's conduct as a path being walked: where you are headed, the choices that get you there, and the destination they reach. So a person has good ways or evil ways, and to walk in someone's way is to live the way they live. This is the word's signature, and it carries the most weight in the wisdom books and the prophets.
From there the word rises to its highest use. God has his ways: both the manner of life he prescribes for his people and his own deeds and dealings with them, which are higher than human reckoning. Wisdom literature sets two ways before every person, the way of the righteous and the way of the wicked, and the whole moral life is framed as choosing which road to walk. This two-ways picture, first sharpened in Psalm 1 and Proverbs, later fed the ethical teaching of early Judaism and the New Testament, where the earliest Christians simply called their movement "the Way."
These are not separate words but one word stretched across a range, from the dust of a literal road to the shape of a life. The same Hebrew sentence can hold more than one of these at once, which is part of why the word is so heavily used.
