So, how much vocabulary do we need to know? According to a number of studies, a person needs to know 95% of the words in order to deduce the meaning of the others from the context. (Cf. here and here.) In the Greek New Testament, there are 5400 lexical forms which are used 138,020 times. (BTW, I'm using BibleWorks9's edition of NA27 and the Wordlist Manager for my word statistics. I suspect there are differences depending on the program and text you use.) It doesn't really mean that a person needs to know 5130 (5400 x .95) lexical forms. That's a good thing since there are about 1934 hapax legomenon (i.e., words used only once) in the Greek NT. Rather, a person would want to know about 131,119 (138,020 x .95) words according to their instances in the GNT. This would require a person to know every word that occurs 6 or more times and a bunch of the ones used 5 times in the GNT. That is, one would need to know about 1700 of the 5400 lexical forms. That's way to many for my students to memorize in a semester.
Let's start from the top instead. I like to tell my students that if they know the Greek article along with καί and δέ, they know about 23% of the words in the GNT! Some other stats which provide specifics to the chart at the top of this post.
- The 10 most common words cover nearly 38% of the GNT
- The 18 words used 1000 or more times cover over 44% of the GNT.
- To know 50% of the words in the GNT, you need to know the 27 most common ones.
- The 37 words used 500 or more times cover over 54% of the GNT.
- The 100 most common words cover over 66% of the GNT.
- The 200 most common words cover just about 75% of the GNT.
- The 311 words use 50 or more times cover almost 80% of the GNT.
So what have I decided to do? Given our limited time, given that we are not aiming to speak or write compositions in Greek, and given that we will be using Bible software, I'm going for the 311 words used 50 or more times in the GNT. Students will be asked to learn 30+ words each weeks for 10 weeks. The vocab quizzes will consist of 10 words each and are multiple choice. Students need to get at least 7 of the 10 correct, and they have 3 chances to take the quiz. I'm also going to make life easier for the students by taking the frequency list and sorting it alphabetically. That way, they will have a mix of common and less common words each week.
I've created my own lists of Greek lexical forms ordered either according to frequency or alphabetically. I've added my own glosses which in many cases provide a bit more information than the typical, minimal glosses. If you would like to use these files which are DOCX files you can get them here:
