Nebulous (adjective) – Nebulous (NEB-yuh-lus) can mean hazy, vague, indistinct, or confused. As I used it in today’s essay: “When you think of investing as something as nebulous as putting money into stocks and bonds  (or commodities or futures or real estate or gold mines), you lose the opportunity to examine the difference between different modalities of ‘investing’ – such as trading, speculating, betting, and gambling.”
