What is my wife's uncle to me?
Your wife's uncle is your uncle by marriage. English never coined a formal word for a spouse's uncle — 'uncle-in-law' never caught on — so genealogists say 'by marriage' and most families simply use 'uncle.' He is your wife's parent's brother, with no blood link to you.

Uncle by marriage
English has no single formal word for this relative — “uncle by marriage” is the label genealogists use.
- You
- Your wife
- Her uncle
From the other side, you are their niece or nephew by marriage.
This connection runs through a marriage, not a shared ancestor, so the ancestor chart can't draw it.
