Based on modern linguistic studies conducted in Germany, England, France, and the USA regarding commonly used vocabulary, researchers have found that the first 1,000 essential words cover over 80% of the vocabulary used in regular (non-specialized) texts. The second 1,000 words add an 8-10% increase, with the subsequent sets of 1,000 words progressively contributing smaller percentages. Overall, the first 4,000 words in any language typically cover around 95% of vocabulary in everyday reading and conversations. Beyond this, additional words contribute much less.In Arabic, the distinction between rarely used and frequently used words can be unclear, with unfamiliar and familiar terms often blending. However, daily conversation typically requires no more than 1,000 words, and regular reading texts use no more than 3,000 words. Thus, if a foreign learner knows the 1,000 most common words used in daily speech, they will be able to communicate effectively. Knowing 3,000 common words will enable them to understand the majority of what they read. This approach simplifies learning Arabic for non-native speakers, saving them time and effort by focusing on frequently used words.
