Question

Fill in the blank with correct word to complete the proverb. 
"Blood is ____ than water."

Accepted Answer

The correct answer is Option 1, "Thicker".

**Explanation for Option 1 (Thicker):**
The proverb "Blood is thicker than water" is a well-known idiom that means family relationships and loyalties are stronger and more important than relationships with people outside the family (such as friends or acquaintances). The word "thicker" in this context is used metaphorically to convey greater density, strength, and importance. It implies that the bonds of kinship are more substantial and enduring than other connections. Therefore, "thicker" is the correct word that completes this proverb, accurately reflecting its established meaning about the primacy of family ties.

**Explanation for other options:**

*   **Option 2 (Thinner):** If the proverb were "Blood is thinner than water," it would imply the opposite of its actual meaning. It would suggest that family ties are weaker or less significant than other relationships, which contradicts the universally understood message of the proverb.
*   **Option 3 (Purer):** While blood might be considered "purer" in certain biological or symbolic contexts, this word does not fit the established proverb. The proverb is about the *strength* and *priority* of family bonds, not their purity. Using "purer" would alter the meaning of the idiom and not convey the intended message of stronger loyalty and connection within a family.
*   **Option 4 (Precious):** Blood is indeed precious, especially in terms of life and health. However, "precious" is not the word used in the traditional proverb "Blood is ____ than water." The proverb specifically uses "thicker" to draw a comparison that emphasizes the comparative strength and importance of family bonds over other relationships. While family is precious, "precious" does not fit the idiomatic structure and established meaning of this particular proverb.
