Syn. -- Advantage, Advantageous, Benefit, Beneficial. We speak of a thing as a benefit, or as beneficial, when it is simply productive of good; as, the benefits of early discipline; the beneficial effects of adversity. We speak of a thing as an advantage, or as advantageous, when it affords us the means of getting forward, and places us on a “vantage ground” for further effort. Hence, there is a difference between the benefits and the advantages of early education; between a beneficial and an advantageous investment of money. [ 1913 Webster ]
