Your Knowledge of Indomitable Cannot Be Tamed

At five punchy syllables, indomitable is an imposing word, so it’s inevitable that some are perplexed by this synonym for impregnable. But it’s not so tough once you break it into parts. The prefix in- (spelled im- before b, m, and p) means “not” in an innumerable collection of English words. (How many have you counted so far?) The common suffix -able means “capable of, fit for, or worthy of.” Combine those two English affixes with the Latin verb domitare (“to tame”), and voila: indomitable. Indomitable was first used in English as a synonym of wild, describing—appropriately enough—things that cannot be tamed, but over time the wildness associated with indomitable developed into a specific kind of invulnerable strength.
