DELF Vocabulary Review: 3,000+ French Words for DELF A1–B2 Exam Prep
Whether you are sitting the DELF to study abroad, apply for a job, or simply prove your level, every part of the exam — listening, reading, writing and speaking — rests on one thing: words. Building a solid DELF vocabulary is harder than it looks, because French asks you to remember the meaning, the pronunciation and the gender of each noun at the same time.
In this review, ChatStick takes a close look at DELF Vocabulary, a new French vocabulary app for iPhone and iPad covering DELF levels A1, A2, B1 and B2. It is designed for a few minutes of study a day, with the goal of words you actually remember on exam day. One thing to know up front: the app is built primarily for Thai speakers, so its interface and translations are in Thai, while every word also carries an English definition.
Why vocabulary matters so much for the DELF
The DELF tests how well you use French in real situations, and the range of topics widens with every level: from introducing yourself, family and food at A1 to the environment, technology, society and giving your opinion at B2. Without enough words, even strong grammar will not stop you from reading slowly, missing key points in a recording, or writing answers that drift off topic. Studying vocabulary organized by level and by exam topic is a far more targeted approach than working through a long, unsorted word list.
Meet DELF Vocabulary by ChatStick
The app brings together more than 3,000 French words grouped by DELF level (A1, A2, B1, B2) and organized into 25 frequently tested topics, including introductions, family, food, travel, housing, work, health, the environment, technology, society, media, culture and opinions. Content is split into 178 short lessons of 8 to 25 words each, so a single lesson takes only a few minutes.
Everything you need for each word on one screen
Each entry goes well beyond a simple translation and includes the details you need to use a word correctly in the exam:
Thai translation and English definition: understand the meaning instantly without a separate dictionary
IPA and the correct article: le, la, l' or les shown with every noun, so you learn the gender along with the word
Example sentences: French sentences with Thai translations that show how the word is used in context
French audio: listen at normal speed or slowed down to practice listening and pronunciation
Synonyms, antonyms and common phrases: plus related words that help your vocabulary grow faster
Key features that help words stick
Smart flashcards: tap to flip, then rate each card Again, Hard, Good or Easy. Spaced repetition brings missed words back more often and spaces out the ones you know well.
10 quiz formats: French to Thai, Thai to French, meaning in context, picture to word, listen and choose, fill in the blank, word matching, sentence completion, true or false, and listen and write — with instant answers and explanations when you get one wrong.
DELF Practice: Quick Sprint (10 questions), Standard Practice (25) and a 45-question Vocabulary Mock Test, each with a summary of your score, accuracy, strong topics and topics to review.
Smart review and word notebook: a daily review queue that puts the words you are about to forget first, favorites, difficult-word marking, filters by level or topic, and “Practice My Words” to build quizzes from your saved list.
Built-in dictionary: search in Thai or French, and find words even without typing accents.
Study habits: daily goals of 5, 10, 20 or 30 words, streaks, XP and achievement badges, progress statistics by level, a weekly activity chart, and an optional once-a-day review reminder.
How to use the app for DELF preparation
Pick the level you are aiming for, such as A2 or B1, and set a realistic daily goal — 10 words a day is a good start.
Work through one topic lesson at a time. Play the slow audio first, then the normal speed, and read each example sentence.
Open the daily review queue every day and rate your flashcards honestly so the spacing stays accurate.
Run a Quick Sprint or Standard Practice regularly, then tap “Practice Weak Words” to drill only the words you still miss.
Before exam day, take the 45-question Vocabulary Mock Test and use the results summary to choose your final review topics.
Tip: a few minutes every day, following the review schedule the app sets for you, beats cramming hundreds of words in a single sitting.
