What does distal mean?
Distal is a chiefly technical adjective meaning located farthest from the center of the body or from the point where a limb attaches. In anatomy, it describes structures toward the periphery: the hand is distal to the elbow, and a fingertip is more distal than the wrist. The term also appears in broader scientific contexts to mean simply the farthest end of a structure relative to some fixed point of reference, as in the distal end of a bone or nerve. Its indispensable opposite is proximal, which denotes the near end, and confusing the two reverses a description completely — one reason precision matters in clinical writing. Derived from Latin roots via words like distant, distal carries a formal, scholarly tone and is essentially confined to medicine, biology, zoology, and related disciplines rather than everyday speech.
(Anatomy) Situated away from the center of the body or from the point of attachment of a limb; toward the extremities.
"The surgeon repaired a fracture of the distal radius."
Almost always paired with an explicit reference point; contrasted with proximal in clinical usage.
(General/scientific) Located farthest from a specified point of origin, attachment, or reference within a structure.
"The dye accumulated at the distal portion of the tube."
Your fingertips are the most distal parts of your arms — every bone from shoulder to fingertip can be described by how 'distal' it is.

Etymology of distal
Distal derives from Latin distare, meaning 'to stand apart' or 'to be distant', combined with the adjective-forming suffix -al. It shares this root with distant and distance, and more broadly with other Latin compound verbs built on stare ('to stand'), such as extant (from extare, 'to stand out'). The word entered English in the early 19th century as anatomical terminology was being standardized.

How distal is actually used
Distal belongs primarily to medical, anatomical, and scientific register; it is rarely used in everyday conversation except in clinical contexts. It is almost always used comparatively or descriptively relative to an explicit reference point, and its technical antonym is proximal. In non-medical prose it may appear figuratively but this usage is uncommon.
Easily confused with distal
Proximal means situated nearest to the point of attachment or the body's center — the exact anatomical opposite of distal.
Distant describes general remoteness in space or time, whereas distal is a technical term for position relative to a specific reference point such as the trunk or site of attachment.
