Getting the Translation Right
The English word "language" translates to idioma in Spanish. That's the standard, everyday term you'll use in conversation, academic writing, and most professional contexts. There's also lengua, which can mean language but carries additional meanings like tongue or dialect depending on context. Most people reach for idioma first and only switch to lengua when there's a specific reason to. The straightforward spelling answer: idioma. I-n-i-d-i-o-m-a. Seven letters. Masculine noun, so it takes "el" or "un" — el idioma, un idioma nuevo. The plural is idiomas. Here's where it gets slightly messier in practice. I was once translating a technical document about multilingual software localization and hit a wall with the word "language." The original English text used it in three different ways within the same paragraph: referring to programming languages, spoken human languages, and linguistic family classifications. If I just translated every instance as "idioma," the Spanish version came out ambiguous and confusing. I ended up using "lenguaje de programación" for code, "idioma" for human languages in a cultural sense, and "lengua" when discussing language families or classification. It took about twenty extra minutes to sort through, but a badly translated spec sheet is worse than a slow translation process.
When Idioma Doesn't Work
People commonly make the mistake of assuming idioma covers every situation. It doesn't. Here are the cases where you'd want something different. Lengua is the other option, and it's more flexible but also more ambiguous. If someone says "hablo tres lenguas," that could mean three languages, three dialects, or in some regions it's used more colloquially. In Spain, "lengua" sometimes carries a political weight around regional languages like Catalan or Basque — calling them simply "idiomas" instead can read as dismissive to certain speakers. If you're writing about Spain specifically, this matters more than you'd expect. Lenguaje is a third option that doesn't directly map to "language" at all in most cases. It usually means "language" in the sense of a mode of expression — "lenguaje técnico" (technical language), "lenguaje corporal" (body language), or a programming language when context is already established. Using lenguaje when you mean idioma sounds either vague or pretentious depending on who's listening.
Pronunciation and Common Mistakes
Pronounce it ee-dee-OH-mah. The stress falls on the o. The d is softer than English — closer to a light th sound in most of Spain, and more like a soft d elsewhere. Don't add an extra vowel after the m at the end. You'll hear people say "idiomah" in their heads when they haven't practiced, and that extra syllable sticks out immediately to native speakers. Another frequent error: lenguage. That's not a word. It looks like a natural mistake if you're thinking about how "language" has a "gu" combination in English and French, but Spanish doesn't work that way. The correct form is either "idioma" or "lenguaje" — never "lenguage." I've seen this in published materials, which shouldn't give you comfort but probably should.

Practical Usage Examples
What does this look like in actual sentences? "¿Qué idioma hablas?" — What language do you speak? This is the most common phrase you'll encounter and the one to memorize first. "El español es un idioma romance." — Spanish is a Romance language. Standard academic usage.
"Necesito aprender un nuevo idioma para el trabajo." — I need to learn a new language for work. Normal conversational context. The phrase idioma materno means native language, and segundo idioma means second language. These are fixed expressions that come up constantly in both casual and formal settings, so they're worth learning as blocks rather than trying to translate each word separately.
Tools and Resources That Actually Help
Duden and WordReference handle basic translation fine. The Real Academia Española's dictionary at rae.es is free and reliable for checking usage notes and regional variation. For pronunciation, forvo.com lets you hear native speakers say the word in different dialects — I recommend filtering by region if you're trying to nail a specific accent, because the difference between the Spanish spoken in Madrid and in Buenos Aires affects how those vowels land. Don't bother with flashcard apps for a single word like this. You don't need spaced repetition for idioma. What you need is exposure to it in context so your brain stops translating from English every time you use it. Read something in Spanish where the word appears multiple times in one sitting, and it'll stick without extra effort.
Where This Approach Falls Short
Knowing how to spell and pronounce idioma is the easy part. The harder part is knowing which word to use in which context, and that only comes from reading and listening enough to internalize the patterns. No single resource will fix that. If you're in a professional translation environment, you'll also run into edge cases where neither idioma nor lengua feels right and you need to restructure the sentence entirely — like translating "natural language processing," which becomes "procesamiento del lenguaje natural," not "procesamiento del idioma natural." The literal translation sounds wrong to anyone who speaks Spanish, and it's a mistake that shows up in AI-generated translations frequently enough to be a tell. There's no shortcut around that except reading the target language regularly and building a sense of what sounds correct versus what sounds like a direct translation.
