Long before the tide fully recedes, the estuary's mudflats become a temporary commons — a stretch of ephemeral ground where wading birds, unencumbered by taxonomy, forage side by side. Their coexistence is less serendipitous than it appears: each species has evolved a slightly different bill length, a subtle divergence that keeps rivalry to a minimum and lets the flock persist.

lasting a very short time

how it works
On a news article, a textbook PDF, a lecture slide, an email — anywhere you're reading, on any site or document on your computer.
Vocabulate keeps the sentence and source the word came from, so you remember what it meant right there — not just a dictionary definition floating on its own.
Come back to Vocabulate and work through your list as flashcards, scheduled with spaced repetition so you review each word right before you'd otherwise forget it.
the review
Rate how well you knew each word, and Vocabulate schedules the next review automatically. Words you know well show up less. Words you're shaky on come back sooner.
