How to learn Spanish — sentences, vocabulary and a free course

Fluera is a free Spanish learning app that teaches vocabulary through sentences, not bare flashcards. You fill in blanks, assemble phrases, type what you hear. Every word — from the course, from a word list or from your own import — lives in one dictionary with one shared schedule.

You can learn Spanish online in your browser or in the app on your phone — progress syncs automatically. Lessons take 5 to 10 minutes. There is no schedule, no teacher and no subscription: you decide when, how much and which words to study.

How to learn Spanish — start with the words that matter

The course starts with the most common Spanish words: greetings, numbers, colors, food, basic verbs. These are the words that appear in every conversation and every text — without them you cannot read or listen. Each lesson adds 3 to 6 new words and drills them inside sentences, not in isolation.

Lessons are 5 to 10 minutes long: about as much as fits into a break or a commute. Short daily sessions work better than occasional hour-long marathons — your brain locks in vocabulary through spaced contact, not through cramming. Learning Spanish is a daily habit, not a weekend project, and a short lesson format supports that habit.

Learn Spanish for beginners — what the course covers

The Spanish course is organized by topic: food, transport, travel, home, work, shopping, health, weather, clothing and dozens more. Each topic is 4 to 6 lessons, each lesson is 3 to 6 words with sentence exercises. By the end of a topic you can understand and form simple statements in that area.

Grammar is built into the same sequence: present tense, past tense, future, noun gender, adjective agreement, prepositions, word order. It appears exactly where it becomes necessary to understand new words. You do not need a separate grammar textbook — everything is woven into the course.

The course covers beginner through solid intermediate. That is enough for travel, casual conversation, reading articles and watching shows with subtitles. If you need more, grow your vocabulary through word lists — import words from real texts, songs and videos you already consume.

Spanish sentences, not flashcards

The problem with Spanish flashcards is that they teach a word-to-translation pair but not how the word behaves in actual speech. A sentence gives you context: what words it combines with, what form it takes, what word order surrounds it. In Spanish this matters more than in English — verbs conjugate heavily and noun gender affects every adjective nearby.

Fluera understands Spanish morphology: 'vio', 'vea', 'viendo', 'vieron' are all forms of one verb, 'ver', and they are folded into a single card. When you tap an unfamiliar form inside a sentence, the system shows the right meaning — not the most frequent translation, but the one that fits this particular context.

Exercise types: fill in the missing word, assemble a sentence from shuffled parts, type what you hear, listen and pick the correct translation. Each type trains a different skill — recognition, recall, listening and spelling. Two correct answers on different days and the word leaves the queue permanently. There is no infinite review loop.

Spanish vocabulary you build yourself

You do not have to follow the course to learn Spanish words. Paste any Spanish text — an article, a recipe, an email, a post — and Fluera extracts the words and ranks them by usefulness for your level. The rarest tokens (proper nouns, one-off slang) land at the bottom; everyday vocabulary you will encounter again lands at the top.

Other ways to fill your dictionary: paste a YouTube link and the service breaks down its subtitles into words. Enter an artist and a song title and Fluera finds the lyrics and extracts the vocabulary. Search the catalog or add words one by one. For every word, including ones not in the database, the system generates pronunciation and usage examples.

Every word from every source enters one dictionary with one shared state. A word learned through a list will not be asked again in a course lesson. A word you failed in a sprint comes back in Practice. No duplication, no parallel decks — one dictionary, one schedule, one progress.

Learn Spanish with songs and videos

Spanish music is one of the best sources of living vocabulary. Enter an artist and a song title — Fluera finds the lyrics and extracts the words. Or paste a YouTube link: the service breaks down the subtitles and offers a set of words ranked by usefulness for your level.

Ranking is not by raw frequency — it is by usefulness. The rarest words (names, slang you will see once) land at the bottom; everyday vocabulary worth remembering lands at the top. Words you already know are flagged and can be skipped. Add the rest with one tap and they join the same training queue as your course words.

This is not a video player with interactive subtitles — you watch the video wherever you like. Fluera extracts the vocabulary and turns it into exercises you work through at your own pace.

Spanish word lists — ready-made and custom

Fluera has ready-made Spanish word lists by level and topic: from the 500 most common words for beginners to themed sets for travel, restaurants, airports and business. There is also an open catalog of lists published by other users — add any list and study it alongside the course.

Build your own list in a spreadsheet-style editor: type a word, get an instant translation lookup. Or describe what you need in plain language — 'words for a trip to Barcelona', 'cooking vocabulary', 'verbs of motion' — and the service suggests a set. Share a finished list by link; someone else can fork it and study it on their own.

You can also study a list with custom settings: choose which word statuses to include, how many words per session, whether to show intro cards, and which exercise types to use. The same single dictionary tracks everything.

Learn Spanish free — a full course with no limits

Fluera is completely free: no lesson limits, no features locked behind a subscription, no ads inside the app. You can learn Spanish free for as long as you need — one lesson a day or ten. Every feature is available from minute one: the course, word lists, video and song import, practice and sprint.

You can start without even signing up: take the first lessons as a guest, and when you decide to continue, create an account and all your progress carries over. Registration is only needed for syncing between devices and for push reminders.

Learn Spanish app — phone, browser, same progress

Fluera runs in any browser and installs as an app on iPhone (App Store) and Android (Google Play). The app and the browser version are functionally identical: one account, one dictionary, one progress. Start a lesson on your phone on the train — finish it on your computer at home.

A home-screen widget shows your current streak and reminds you to study without making you open the app. Push notifications arrive only if you have not studied today and only during daytime hours — the service does not wake you up at night and does not nag more than once.

How to learn Spanish fast — consistency over cramming

The most common reason people quit is not difficulty — it is inconsistency. Two hours on Sunday, then a week off, then guilt and another two weeks of silence. Fluera is built so that you can study Spanish regularly without heroics: one lesson a day, 5 to 10 minutes, no homework and no penalty for a missed day.

A streak counter shows how many days in a row you have studied. It is a gentle guide, not a punishment: a missed day does not erase your progress. A push reminder arrives once a day — only if you have not studied yet. After your first lesson the notification will not come. The service helps you not forget, but it does not turn learning into a chore.

This approach works particularly well with vocabulary: every lesson is a concrete number of words you either learned or did not. Progress is visible in numbers, not in abstract percentages. Yesterday you had 120 learned words, today 126 — that growth is tangible and it motivates you to keep going.

Spanish practice — Practice, Mistakes and Sprint modes

Beyond the course, Fluera has two training modes. Practice collects words you have started learning but have not fully locked in — they come back at intervals and you drill them in the same sentence exercises. Mistakes are separated out: if you got a word wrong in a lesson, it lands in a dedicated Mistakes mode where you can target exactly what is giving you trouble.

Sprint is a 60-second speed round across words you already know. A timer, a stream of questions, a counter of correct answers. It is not a full lesson — it is a quick warmup for days when time is short but you do not want to break the streak. Sprint is great before a trip — it refreshes words you studied weeks ago but have not pulled from memory recently.

Both modes work with the same single dictionary: if a word is due, it appears in Practice regardless of where it entered your vocabulary — from the course, from a list or from a video import.

A Duolingo alternative built around your vocabulary

In a gamified course, the unit of value is the daily session — you complete it and move on. In Fluera, the unit of value is the word. You choose which words to learn, you see their state, and they graduate out of the queue when you know them. The course and your own lists write to the same dictionary — there are no separate silos.

In a flashcard app, a card set is a string-matching exercise. Here a row is a linguistic object: inflected forms fold into one entry, the card carries examples and audio, sentence exercises come from the same data, and the state is shared with everything else. Four import paths do the authoring work that Anki and Quizlet leave to you.

If you have been looking for apps to learn Spanish that combine a structured course with the freedom to add your own words, Fluera is worth a try. It is free, there is nothing to lose, and a guest session lets you see how it works before you sign up.
