Humans are naturally curious: our species seems to excel at posing questions that are well and truly baffling. You know, the kinds of questions that are paradoxical beyond the point of resolution: "Which came first, the chicken or the egg?" "If a tree falls in a forest and no one is around to hear it, does it make a sound?"
Lastly, the most brain-bending of all: "Is a thumb a finger?"
According to the folks at Grammarly, the almighty thumb dare not be described as part of the finger family. These word nerds reckon that although many people fail to make the distinction, the thumb should always be declared a "digit." In accordance with this concept, the Oxford dictionary defines fingers as “Each of the four slender jointed parts attached to either hand...” There's no denying that the thumb "digit" does physically differ from its neighbouring phalanges. This lone ranger also differs in its superior performance skills. Without our opposable thumbs, humans wouldn't be able to pick up and use important things like nail polish.
