However, it's important to understand that this phrase is rarely used literally in Spanish. It's often used metaphorically to describe:
* Someone with great strength or power: Think of someone with a "powerful lineage" or "noble blood."
* Someone with a strong personality or character: It could describe someone who is "bold," "brave," or "determined."
* Something of great importance or value: This could refer to a "significant" or "monumental" event.
The exact meaning of "sangre grande" will depend on the context in which it is used.
