Thanks to years spent in isolation, Snow is a woman of few and especially cautious words (and, sadly, assumes others to be the same), which is a nice way of saying "her conversational skills are rusty." If given the chance to listen or to speak, she'll choose the former in most cases. People almost always have stories worth being told, after all, so an open ear is worth offering. When pressed, her speech primarily consists of questions and matter-of-fact statements; however, she isn't outright rude or snarky, just honest...for better or for worse.

This has the fringe benefit that she often offers up genuine kindness straight from her heart as often as not. Her intentions are not to seem cold, nor is she not entirely without a sense of humor.

Her relative quiet means that when she does choose to pontificate, people listen. Behind her words, there's the passion of complete faith in whatever cause she aligns herself with.

From IMDB:

The Huntsman: What the hell's going on? Who are you? Why does the Queen want you dead?
Snow White: She wants everyone dead. All of us!
The Huntsman: What makes you so damn valuable?
Snow White: You should know. You're the one hunting me.
The Huntsman: Forget it. I should have never got involved in the Queen's business.
Snow White: Where are you going?
The Huntsman: Getting away from you. You're trouble, is what you are.
Snow White: I need to get to the Duke's castle. There's an army there.
The Huntsman: Oh the Duke's army? Bunch of farmers with milkmaids and pitchforks. I know sheep that have more fight in them.
Snow White: I'm valuable. That's why you're here, isn't it? If you return without me you're dead. If you leave me I'm dead.
The Huntsman: Just for argument's sake, how much reward?
Snow White: However much is enough.
The Huntsman: At least thirty gold pieces.
Snow White: One hundred. Help me.
The Huntsman: Who are you?
Snow White: Maybe you should have asked the Queen that.
The Huntsman: I don't trust you.
Snow White: I've given you my word.
The Huntsman: I still don't trust you. But you have a deal.

Muir: That seat's not taken, if that's what you were about to ask.
Snow White: I want to thank you.
Muir: It's only a log. There's no need to thank me.
Snow White: No, for before. For defending me.
Muir: Your father was a good man. The kingdom prospered. Our people prospered.
Snow White: There were more of you?
Muir: Aye.
Gort: Yeah. The men you see before you and many, many more went deep into the caves. We were noble gold miners because we could see the light in the darkness. Gus, you were just a boy but you remember. When we returned to the surface, there was nothing. The land was blackened. Everything, everyone was gone. Was dead.
Muir: That was the month your father died.
Snow White: I'm very sorry.
-
Snow White: Death favors no man. We must ride like thundering waves under the tattered battle flag of my father.
Duke Hammond: You must rest.
Snow White: We have rested long enough. Frost to fire and fire to frost. Iron will melt. But it will writhe inside of itself! All these years, all I've known is darkness. But I have never seen a brighter light than when my eyes just opened. And I know that light burns in all of you! Those embers must turn to flame. Iron into sword. I will become your weapon! Forged by the fierce fire that I know is in your hearts! For I have seen what she sees. I know what she knows. I can kill her. And I'd rather die today than live another day of this death! Who will ride with me? Who will be my brother?

Snow White: [captured by the Huntsman] Will you help me? Please? Please, the Queen is going to kill me.
The Huntsman: Sure she is
Snow White: She's going to rip out my heart!
Finn: Quick work! Well done, huntsman. Hand her over.
The Huntsman: What do you intend to do with her?
Finn: Why do you care?
The Huntsman: You want her give me what I was promised.
Finn: You did your job well. Now, keep your word.
Snow White: He'll kill us both.
The Huntsman: Shut up.
Snow White: He will!
The Huntsman: I said, shut up.
[points sword at Snow White]
The Huntsman: I'll keep my word when the Queen keeps hers. Where is my wife!
Snow White: He's going to betray you.
Finn: My sister has many powers. She can take life away or sustain it, but she can't bring your wife back from the dead, you fool!
-
The Huntsman: I told you to run.
Snow White: If I had, you'd be dead.
-
Finn: Are you always awake when I watch you?
[touches Snow White]
Snow White: You've never come in before.
Finn: My sister won't allow it. She wants you all to herself.
Snow White: I'm afraid of her.
Finn: And not of me?
[leans closer to Snow White's face]
Snow White: No.
Finn: Fear not, Princess. You will never again be locked in this cell.
Snow White: What does she want from me?
-
Snow White: Do you drink to drown your sorrows? Or your conscience?
The Huntsman: What concern is it of yours why I drink?
Snow White: I suppose a man's sorrows are his own.
The Huntsman: What does a young girl like you know about sorrow?
-
Snow White: William. It's as if nothing's changed here. The world seems beautiful again.
William: It will be when you are queen. The people of this kingdom hate Ravenna with every fiber.
Snow White: I used to hate her. Now I feel only sorrow.
William: Once people find out you're alive they will rise up in your name.
Snow White: It takes more than a name.
William: You are your father's daughter. The rightful heir. If I had a choice I'd take you far away. Keep you safe by my side. But I have a duty and so do you.
Snow White: How do I inspire? How will I lead men?
William: The way you led me when we were children. I followed you everywhere. I ran when you called. I would have done anything for you.
Snow White: That's not how I remember it. We used to fight all the time. And argue.
-
William: I'm sorry I left you.
Snow White: You didn't.
William: If I'd have thought you were alive I would have come for you.
Snow White: We were children, William. You're here now.
-
The Huntsman: Why didn't you tell me? Because I'd think it was too difficult a task? You would be right.
Snow White: I didn't trust you. I'm sorry.
