Life Vs life insurance

Given that the term "Life insurance" was coined, I always assumed that life insurance and life insurance are names for the same form of insurance. But if you belong to my category be broken heart because several financial wiz kids have got it wrong too. Life insurance and life insurance make two different financial roles and are from East to West when it comes to costs.
But before going to the nuances of what are the main differences between the two forms above i.e. insurance and insurance. Let's just why it is necessary to obtain "insured"?
In our youth, our future planning can be a tedious job and a burden much time. In view of where would be the time to shop for these products when we try to follow most of the work and home life. But even if all things in life were predictable, died with certainty cannot be predicted. But if the unthinkable would happen, you see your spouse and your dependants financially safe and healthy for the rest of their lives? If this is not the case, then a policy of life insurance is a must.
Life insurance has been defined by dictionary.com as a "designated insurance that guarantees a specific beneficiary sum upon the death of the insured and the insured if he or she lives beyond a certain age.".
But life insurance, on the other hand, is different. Life insurance is a hybrid combination of insurance and investment. "A policy of life insurance" pays a sum of money equal to the higher or a minimum supported by the insurance policy or its assessment of the investment clause. Thus, the value of your investment depends on the performance of the business of insurance to investment and growth.
Each year the insurance company adds annual premium to the value of your insurance policy, and there is a terminal bonus at the end of your mandate. Therefore, as the years pass by your insurance policy increases in value as keep adding investment premiums on. But unlike life insurance if you die during the term of life insurance, the insurance company would pay out the greater of the minimum sum secured or the accumulated value of the annual premiums for investment.
