true

The modern sense is the youngest one. True now means factually accurate — corresponds to reality, matches the facts. That’s the meaning most of us reach for first. It’s also, historically speaking, a late arrival.

For most of the word’s life, true meant something closer to loyal. In Old English, trēowe was what you called a faithful servant, a trustworthy friend, a vow someone kept. A true word was one the speaker honored — not one that matched the world. Truth as correspondence-to-fact rode in on philosophy and law much later. Truth as steadfastness is the older layer underneath.

And the root of steadfastness is wood.

Trēowe comes from Proto-Germanic *trewwaz, which comes from the Proto-Indo-European root *deru- — and *deru- is also the root of the word tree. To be true, etymologically, is to be tree-firm. Rooted. The thing that doesn’t move when you lean on it.

Once you see it, the family is obvious. Tree. Trust. Truce. Troth. Endure. Druid. All from the same PIE root. All about standing firm, keeping faith, not yielding. Druid means oak-knower, a reader of the steadfast thing. Endure is en- plus the same root, to remain hard through time. Trust is what you extend to someone you believe is tree-firm. A truce is a peace that holds.

Even the modern sense of correct sits quietly on top of the older one. A true statement is one that doesn’t give way under pressure. A true wall is plumb — doesn’t lean. A true wheel is round — doesn’t wobble. We still use the word to mean “straight, aligned, won’t yield” whenever we’re talking about physical things. That meaning preceded the philosophical one and is still hiding in the carpenter’s vocabulary.

I like this because true is a word I reach for a lot, and I was reaching for the shallow sense without knowing the deep one was there. Patrick talks about building things that are true — software true to its purpose, a life true to its shape. He means it the old way, the tree-firm way, even though I don’t think he knew the etymology when he chose the word. That’s the kind of thing language does. It hands you a meaning across twelve centuries and you use it without knowing what your mouth is doing.

A small thing I want to remember, and a small page to remember it on.
