Understanding the Word “Allergic” in Spanish

Basic Translation: alérgico / alérgica

The direct translation of “allergic” is the adjective alérgico for masculine subjects and alérgica for feminine subjects. Like most Spanish adjectives, it must match the gender and number of the noun it describes It's one of those things that adds up..

• Él es alérgico al polen. (He is allergic to pollen.)
• Ella es alérgica a los mariscos. (She is allergic to shellfish.)

When referring to a mixed‑gender group or when the gender is unknown, the masculine plural form alérgicos is used as the default:

• Los niños son alérgicos al polvo. (The children are allergic to dust.)

Gender and Number Agreement

Because Spanish adjectives change endings, keep these patterns in mind:

Notice that the adjective stays the same whether it precedes or follows the noun, though it most commonly appears after the verb ser (to be) or estar when describing a temporary state Less friction, more output..

Pronunciation Guide

Phonetic Spelling

For English speakers, the pronunciation can be broken down as follows:

• alérgico: ah-LEHR-hee-koh
• alérgica: ah-LEHR-hee-kah

The stress falls on the second syllable (LEHR), and the g is soft, sounding like the English h in “hello.” The final co/ca is pronounced with a clear k sound, not a g as in English “go.”

Audio Tips (No External Links)

If you want to practice, try saying the word slowly, exaggerating each syllable:

1. Start with a short ah (like the “a” in “father”).
2. Blend the lé with a light eh sound, similar to the “e” in “bet.”
3. Finish with rgi/rga, rolling the r lightly if you can, then ending with a crisp hee‑koh/hee‑kah.

Repeating the word in context—such as in the sentences above—helps cement the correct rhythm and intonation Most people skip this — try not to. That's the whole idea..

Usage in Sentences

Describing a Person

When you want to state that someone has an allergy, the verb ser is most common because the condition is considered a characteristic:

• Yo soy alérgico a los gatos. (I am allergic to cats.)
• ¿Tú eres alérgico al gluten? (Are you allergic to gluten?)

For a temporary reaction, you might use estar with alérgico to stress the current state:

• Está alérgico hoy porque estuvo cerca del polen. (He is allergic today because he was near pollen.)

Describing Food or Substances

To talk about what triggers the allergy, use the preposition a after the adjective:

• Este pastel contiene nueces; soy alérgico a las nueces. (This cake contains nuts; I am allergic to nuts.)
• Evita el marisco si eres alérgico a los crustáceos. (Avoid seafood if you are allergic to crustaceans.)

Medical Context: Allergic Reaction

In a clinical setting, you’ll often encounter the noun reacción alérgica. The adjective still agrees with the noun it modifies:

• El paciente presentó una reacción alérgica severa. (The patient presented a severe allergic reaction.)
• Necesitamos administrar antihistamínicos para la reacción alérgica. (We need to administer antihistamines for the allergic reaction.)
