Meaning
gift of God; short for Theodore
Also written Théo.
The story
Theo is a short form that quietly stopped needing the long one. It belongs to Theodore, from the Greek theos and doron, gift of God, and our own verified short-form records name that parent. It can also stand behind Theobald, a different name from different roots, so the careful sentence is that most Theos today are Theodores. The curve is one of the clearest revivals in our data. Theo ran to about 1,800 babies in the 1920s, thinned to under 400 in the 1960s, stayed low through the 1980s, and then turned: more than 8,000 in the 2010s and over 21,000 so far this decade. That is roughly fifty times its low point. Vincent van Gogh's brother and lifelong correspondent was a Theo, which is a small thing to carry, but it is part of why the name has always sounded like someone worth writing to.
