Etymology
Origin of insuperable
First recorded in 1300–50; Middle English word from Latin word insuperābilis. See in- 3, superable
Explanation
Perhaps if you are a superhero, you can tackle an insuperable problem — one that is considered impossible to overcome. Insuperable is an adjective that is often paired with nouns like difficulty, obstacle, and barrier. An insuperable difficulty is not just difficult; it’s impossible. And an insuperable obstacle is not like a hurdle on a running track that slows you down a little; it stops you entirely. The opposite of insuperable is, of course, superable, though it’s less commonly used than its negative counterpart.
