How to Say “Unspeakable” in Spanish

indecible
/indeθible/from spelling rules
The English phrase 'unspeakable' is translated into Spanish as indecible.
When used to mean 'extremely bad', indecible carries a heavy connotation of something so horrific that it defies words. It can also be used more broadly to describe something that is too great or intense to be described, whether the context is positive or negative. To express that something is 'entirely' unspeakable, you can use the adverb completamente.
Meaning: extremely bad (adj)

Which one should you use?

While indecible is the standard term, there are formal synonyms available depending on your specific nuance. Use inexpresable (inexpressible) or indescriptible (indescribable) to indicate that something cannot be adequately described. You may also use inenarrable, which is a formal term implying that something is beyond description or narration.

How does it change in a sentence?

As an adjective, indecible must agree in gender and number with the noun it modifies, such as using indecibles for plural nouns.

How do you pronounce it?

/indeθible/

Did you know?

  • To describe an unspeakable tragedy in a casual setting, Spanish speakers often use the idiom no tiene nombre, which literally means 'it has no name'.
  • In some Spanish-speaking regions, using the word indecible to describe a person's behavior can be a subtle way of implying their actions were scandalous or shameful.
