Spanish (or Castilian) is a very rich language, so much so that, depending on the syllable that is pronounced with more force, its words are divided into acute, flat (also known as grave) and esdrújulas. esdrújulas words They are easy to identify because they follow a very clear accentuation rule: they always have an accent mark. Throughout this article, we will delve into what proparoxytone words are, how to accent them correctly, and we will offer various examples, along with other interesting aspects of their use in the Spanish language.
What are esdrújulas words?

The esdrújulas words are those whose stressed syllable, which is the one pronounced with the most force, is on the third-to-last syllable. Unlike the acute and grave syllables, the accentuation rules for the proparoxytones are very simple: They always have an accentregardless of the letter they end with. Typical examples of proparoxytone words include terms like fantastic, microphone o esdrújula. They all have in common that the greatest force falls on the penultimate syllable, highlighted with an accent.
Comparison between proparoxytone, acute and grave words

To better understand what proparoxytones are, it is useful to compare them with acute and grave words:
- Sharp words: the stressed syllable is the last one and they only have an accent mark if they end in a vowel, ‘n’ or ‘s’ (Accident, baby).
- Serious or simple words: the stressed syllable is the penultimate one and they are accented if they do not end in a vowel, ‘n’ or ‘s’ (easy, pencil).
- Words esdrújulas: the stressed syllable is the penultimate one and always has an accent, regardless of the ending (technical, The music).
Rules for accentuation of proparoxytones
The accentuation rules The rules for proparoxytone words are very simple: all of these words, without exception, have an accent mark on the antepenultimate syllable. This makes them a special group in Spanish because they do not depend on the common endings of other word categories. Furthermore, these words can appear in a wide variety of contexts. They can be nouns (America), adjectives (Speed), conjugated verbs (draw it for me), among other grammatical categories.

- Air Freight: presents a hiatus in the syllable éprisoner.

- Gloomy: uses a triphthong.
In all these cases, the penultimate syllable is still stressed and, therefore, must be accented.

- Eagle: The eagle is a bird of prey that lives in the mountains.

Overstressed words: adverbs with “-mente”

A special case of proparoxytones are adverbs ending in “-mente”. These adverbs only have an accent if the adjective from which they are derived originally had one. For example:
- Easily: derived from easy, which has an accent.
- Nimbly: derived from agile, which has an accent.
- Quickly: derived from Speed, which has an accent.
