Able to be expected; likely to occur or happen in a normal or reasonable way.
From expect (from Latin expectare: ex- + spectare, to look at, to watch) plus the suffix -able (capable of). The word entered English in the 17th century to describe things that are reasonable to anticipate.
This word is rarer than 'expected,' but scientists and philosophers love it because it means 'following the laws of probability or reason'—it's more precise than just saying something 'will happen.'
