One common mistake is confusing reservoir with preserve or conserve. While a reservoir stores resources, to preserve or conserve means to protect or maintain something.
Another error is mispronouncing the word as re-ZER-voir instead of REZ-er-vwar. Understanding the word reservoir is crucial for the SAT, not just for vocabulary questions, but also for reading comprehension passages that might discuss water management, energy production, or even metaphorical uses in fields like economics or psychology.
Remember, a reservoir isn’t just a body of water – it’s a stored supply of anything valuable, be it knowledge, resources, or potential.
