Discern and distinguish both cut through sameness, at different jobs. To discern is to make something out — to perceive what is faint, hidden, or easily missed: a shape in fog, a motive behind politeness. To distinguish is to tell things apart — to see or mark the line between two: fact from opinion, the real from the forged. Discerning finds the signal; distinguishing draws the boundary.
Both descend from Latin verbs of separating, and the separation happens in different places. Discernere separates a thing from its background: effortful perception, squinting included — you discern what barely shows, never what is obvious. Distinguere separates things from each other: the line between categories, marked or noticed — you distinguish X from Y, or between X and Y. The derivatives carry the split faithfully: a discernible trend is one you can just make out; a distinctive style is one nothing else could be confused with; and a discerning critic tells good from almost-good for a living.
discern
To discern is to make something out — to pick a signal from the noise, a shape from the fog, a true motive from a polite one. From the Latin discernere, 'to separate', it always implies effort or fineness of perception: you discern what is faint, hidden, or easily missed, not what is obvious. To discern a pattern is to scrutinize until it resolves; to be discerning is to notice distinctions others overlook. What is conspicuous needs no discerning at all.
distinguish
To distinguish is to tell things apart — to perceive or mark the line that separates one from another. You distinguish a wolf from a dog, fact from opinion, the real from the forged. It overlaps with differentiate and discern, but distinguish leans on noticing the difference, where differentiate often means actively creating one. A second sense turns the word on its subject: to distinguish yourself is to stand out by merit and earn distinction. The Latin distinguere meant to separate by marking points between things.

The static and the prism. Discerning is the circle stepping out of the grey snow — one faint thing rescued from its background by narrowed attention, and lost again the moment focus slips. Distinguishing is the prism fanning white light into named colours — several things, present all along, spread far enough apart to tell which is which. Ask what the sentence is doing: rescuing one faint signal (discern), or drawing the line between two knowns (distinguish). One squints; the other sorts.

The derivative families are the daily workhorses: a discernible difference (just detectable) is weaker than a distinct one (plainly separate); a discerning reader judges finely, while a distinguished professor has earned distinction — note how distinguish alone turns on its subject, since to distinguish yourself is to stand out by merit. Grammar: discern takes a plain object or 'discern between'; distinguish runs both 'from' and 'between'. Distinguish's contest with differentiate has its own page on this site.
Both verbs are exam furniture: reading items ask what can be discerned from the passage (inference from faint evidence) and prompts order you to distinguish between X and Y (draw the boundary). In writing, 'a discernible trend' hedges precisely — visible, but only just — while 'a clear distinction' commits. Bank the personal sense too: candidates who distinguish themselves earn the adjective distinguished, and 'a discerning audience' compliments taste, not eyesight.
