《关于英语单词的长度》
虽然数据统计分析的方式很多，但是总体上的结论大致相同，基本上都指向了5个字母。
这里我给出额外的几个数据参考：
首先，在超巨量的词汇平均之下，英语单词的长度也仅有9.1个字母，所以本站按字母排序收录截至18字母。
其次，我按单词词频排序的计算结果如下：
- 词频最高的1000个单词平均长度为5.2个字母
- 词频最高的2000个单词平均长度为5.7个字母
- 词频最高的3000个单词平均长度为6.1个字母
- 词频最高的4000个单词平均长度为6.3个字母
- 词频最高的5000个单词平均长度为6.4个字母
而词频最高的5000已经可以覆盖英语日常95%以上的文本量。
所以，在学习英语记单词这一块根本不需要为长度担心。
Regarding the length of English words
Although there are many ways to perform statistical analysis of data, the overall conclusion remains roughly the same, basically pointing towards words with five letters.
Here, I provide a few additional data points for reference:
Firstly, on average, the length of English words, considering the immense vocabulary, is only 9.1 letters. Therefore, this website includes words up to 18 letters in alphabetical order.
Secondly, the results of my calculations based on word frequency sorting are as follows:
- The average length of the 1000 most frequently used words is 5.2 letters.
- The average length of the 2000 most frequently used words is 5.7 letters.
- The average length of the 3000 most frequently used words is 6.1 letters.
- The average length of the 4000 most frequently used words is 6.3 letters.
- The average length of the 5000 most frequently used words is 6.4 letters.
The 5000 most frequently used words already cover more than 95% of daily English text.
Therefore, there is no need to worry about the length of words when learning English vocabulary.
