Is it Necessary to Learn Grammar?
Since the two building blocks of language are vocabulary and grammar, the answer in a nutshell… is oui (yes).
Although it’s entirely possible to learn to hold a conversation in French solely through immersion, speaking with true proficiency requires conscious study of its grammatical rules. It’s also important to remember that language isn’t made up of one skill alone; it consists of an ability to master 4 skills with accuracy: reading, writing, listening, and speaking.
A holistic approach to learning French places emphasis on learning both vocabulary and grammar - the inextricable components of language.
