Prioritize commonly used vocabulary
Similar to any project, learning a language is best approached by focusing on the smallest achievements first. You may first start by concentrating on the words and phrases that are used in conversation the most. Think about how frequently you engage in conversations about hobbies, family, or other everyday topics.
A list of the most commonly used words in whatever language you're learning should be available online or in a textbook. A lot of study programs on apps and online sources start off with exercises that are meant to reinforce the commonly used speaking style. Even if you are unable to speak the language yourself, having a solid comprehension of its basic vocabulary should enable you to understand what is being said.
