Agua is feminine, even though you normally say el agua. Spanish uses the article form el immediately before a singular feminine noun that begins with a stressed a sound. The noun’s gender does not change: say el agua fría, esta agua, and mucha agua. In the plural, say las aguas. This is a particular article pattern, not a rule that turns feminine nouns masculine or changes every word in front of them.
Listen for a stressed initial a sound
El agua está fría. “The water is cold.” The first syllable of agua is stressed. Immediately before it, the singular definite article takes the form el. Other examples include el águila (the eagle), el alma (the soul), and el hacha (the axe). Silent h does not block the pattern: hacha begins with the same relevant vowel sound.
Stress matters. La amiga and la arena keep la because their initial a sound is unstressed. Do not switch to el for every feminine noun starting with the letter a. The rule is about a particular sound in a particular position.
Adjectives and most determiners remain feminine
Because the noun stays feminine, its adjectives remain feminine: el agua limpia (the clean water), el águila blanca (the white eagle), el hacha afilada (the sharp axe). Avoid el agua frío. The correct adjective is fría.
| Use | Correct expression |
|---|---|
| This water | esta agua |
| Much water | mucha agua |
| So much water | tanta agua |
| All the water | toda el agua |
| The water is clean | El agua está limpia. |
The visible el can tempt you to copy masculine endings across the phrase. Instead, keep the noun’s gender in mind and apply the article rule only where it belongs.
An intervening word brings back la
The special definite-article form applies when the article is immediately before the noun. Compare el agua fría with la fría agua. The second phrase is more literary, but it shows the principle: an adjective now separates article and noun, so la is used.
A more useful everyday example is la misma agua, “the same water.” Say la misma agua de ayer, not el misma agua. Similarly, la majestuosa águila uses la before the adjective, while el águila majestuosa uses el directly before the noun.
This is not a reason to move adjectives around artificially. Use natural word order, then apply the article that fits that phrase.
Use las in the plural and learn un agua as a pattern
In the plural, use feminine las: las águilas blancas, “the white eagles,” and las aguas frías del río, “the river’s cold waters.” Most everyday references to water are singular, but plural aguas is useful in geographical and other contexts.
The indefinite article commonly appears as un in the corresponding singular pattern: un águila blanca, un hacha pequeña. RAE also recognizes una in these cases, although the shortened form is generally preferred. Learn the common un pattern without declaring every una example impossible.
Alguna and ninguna also normally shorten directly before these nouns: algún águila, ningún hacha. Other words, such as esta and mucha, keep feminine forms.
Check the article and the adjective separately
Choose the correct words and explain which rule each choice follows.
- El agua está frío / fría.
- Este / Esta agua es para ti.
- Vimos los / las águilas.
- Quiero el / la misma agua.
- El / La arena está caliente.

1. fría: agua remains feminine. 2. Esta: the special article pattern does not turn this demonstrative masculine. 3. las: plural feminine article. 4. la: misma separates article and noun. 5. La: the first a of arena is not stressed.
Practice a short request: ¿Me das un poco de esta agua fría? “Can you give me a little of this cold water?” Both esta and fría remind you of the gender.
Common questions about el agua
Does agua have an accent mark?
No. The stress falls naturally on the first syllable under Spanish spelling rules. A stressed sound does not always need a written accent.
Is it la agüita or el agüita?
La agüita. In the diminutive, the stress moves away from the initial a. The pronunciation and stress of the actual noun determine the article pattern.
Does every feminine word beginning with stressed a take el?
This guide describes the ordinary noun pattern. There are exceptions, including names of letters such as la a. Learn those separately rather than extending the pattern to every kind of word.
