To change the way someone or something looks, so completely that it seems lifted into something more beautiful. A sunset can transfigure a plain grey street; joy can transfigure a face. It is a formal, literary verb — you will find it in novels, poems, and art writing far more than in speech. Two things about how it is really used. First, it is most often passive: 'her face was transfigured by happiness' is much more common than 'happiness transfigured her face', though both are correct. Second, the change is usually shown as coming from light, or from a strong feeling, or from something spiritual — not from work or tools. A builder does not transfigure a house; a painter does not usually transfigure a canvas. Morning light transfigures a house. Like the noun, it echoes the Bible story where Jesus's appearance shines on the mountain, and that echo is part of why the word feels solemn. If you simply mean a big change, 'transform' is the ordinary verb and is safe everywhere.
