I agree with everyone else. Where I live, it's OK to call the daughter of your spouse a "stepdaughter" (or stiefdochter as it's called in Dutch) even if you haven't legally adopter her.

I have never heard of a "half-daughter" (and I can't imagine how you can have a "half-daughter", she is your daughter or she isn't

), though to me that implies that you and your daughter are related. However, you and your stepdaughter do not share any genes*. Half-siblings share on average 25% of their genes.

*Scientfically speaking this isn't exactly true, I said it for the sake of simplicity.

People often skip the step- part.

To clarify, there is no term "half-daughter" or "half-son."

Here's somebody's half-daughter.

. Note that the suggested term 'half-daughter' makes no genetic sense - it can't be done. Children that share one parent are half-brothers/sisters; half* their genes are the same. I suppose you could crefer to a man's niece as his 'quarter*-daughter' - we just don't.

PS * This was wrong; I was forgetting my Mendelian peas (let alone qs). I guess my 'quarter-daughter' should have been 'eighth-'. Biology was never my Thing.

Full siblings share on average 50% of their genes with each other, half-siblings share only 25% on average.
