Definition: The word "insurance like root" is not a word itself, but rather a phrase that can be used in a sentence to describe something as similar or closely related to another. In other words, it's a metaphorical expression that suggests that if you are applying for insurance, it might feel like you're paying for an expensive car or house because you're borrowing money from someone else (the "insurance" here being the loan), but in reality, you're actually getting something more valuable and necessary: your safety and security. For example, you might say: "I'm considering applying for insurance to protect myself against unforeseen expenses or risks that are similar to those I face in my day-to-day life." Or, even simpler, "You've probably heard of the phrase 'insurance like root' - it's a metaphor to describe someone who is borrowing money from others without paying back what they owe."
