The Largest Vocabulary In Hip Hop

Rappers, ranked by the number of unique words used in their lyrics

Updated on January 21, 2019

with 75 new rappers including Brockhampton, Death Grips, Lil Uzi Vert, Travis Scott, and Migos

This project was originally published in 2014 and recently updated in January 2019 with newer lyrics data and 75 additional artists, including Lil Uzi Vert, Lil Yachty, Migos, and 21 Savage.

It compares the number of unique words used by some of the most famous artists in hip hop (that is, an example of a quantitive view of lyricism, once proposed by Tahir Hemphill). I used each artist’s first 35,000 lyrics. This way, prolific artists, such as Jay-Z, can be compared to newer artists, such as Drake.

35,000 words covers 3 to 5 studio albums and EPs. I included mixtapes if the artist was short of the 35,000 words. Quite a few rappers don’t have enough official material to be included (for example, Biggie, Chance the Rapper, Queen Latifah, and El-P).

Since the original release, there’s now a notable trend of fewer unique words among newer artists. This is easier to see in the following chart, where I highlighted each artist’s primary decade, based on album release dates for their vocabulary calculation (the first 35,000 lyrics).

by era1






(1) Since this analysis uses an artist’s first 35,000 lyrics (prioritizing studio albums), an artist’s era is determined by the years the albums were released. Some artists may be identified with a certain era (for example, Jay-Z with the 1990s, with Reasonable Doubt in 1996, In My Lifetime, Vol. 1 in 1997, etc.) yet continue to release music in the present day.

Some of the newer artists wield a smaller vocabulary comparatively, but this is not because hip hop has “dumbed down.” The genre has evolved; it has moved away from complex lyricism toward elements traditionally associated with pop music: repetitive song structure and singing (Joe Carmanica recently wrote about this trend for the New York Times, arguing that it was led by Drake, who popularized the rapping-and-singing formula over the past decade).

A better benchmark for Lil Uzi Vert’s word count (2,556) might be those of pop artists, such as Beyonce (2,433 words), or even one his major influences: Marilyn Manson (2,466 words).

There are also genre-bending artists. If Childish Gambino’s Awaken, My Love! is less hip hop in the traditional ’90s boom-bap sense, is it fair to compare it to vocabulary-dense Wu-Tang albums? Genre matters in vocabulary calculations—check out the chart below, which takes 500 random samples of 35,000 words from rock, country, and hip hop.

In short, if artists depart from hip-hop song structure, we’d expect their vocabulary to go down in the number of unique words.

That said, the results are still directionally interesting. Of the 150 artists in the dataset, let’s take a look at who is on top.

#1 - Aesop Rock

When I first published this analysis, I excluded Aesop Rock, figuring he was too obscure. The Reddit hip-hop community was in an uproar, claiming that Aesop would absolutely be #1. Sure enough, Aesop Rock is well above every artist in the dataset, and I was obliged to add him to the chart.

#2 - Busdriver

For the most recent update, I pored over requests from readers, and Busdriver was most common on folks’ wishlists. He and Aesop Rock are the only rappers with more than 7,000 unique words in their first 35,000 lyrics.

#4, #5, #7, #10, #15, and #20 - Wu-Tang Clan Ain’t Nuthing Ta F’ Wit

Wu-Tang Clan at #5 is impressive given that 10 members, with vastly different styles, equally contribute lyrics. Add the fact that GZA, Ghostface, Raekwon, and Method Man's solo works are also in the top 20 – notably, GZA is at #4.

#28, #54 - Outkast and E-40

Of course E-40 is in the top 20%; he’s considered to be the inventor of many slang terms. Just a few that he’s been responsible for coining or popularizing: “all good,” “pop ya collar,” “shizzle,” and “you feel me.”

Outkast’s expansive vocabulary is definitely a function of their style: frequent use of portmanteaus (for example, “ATLiens,” “Stankonia”), southern drawl (for example, “nahmsayin,” “ery’day”), and made-up slang (for example, “flawsky-wawsky”).

#49 and #59 - Busta Rhymes and Twista

Since both rappers are known for their speed, it’s nice to see that their verses are just as lyrically diverse as their peers’.

So what's all this mean?

io9 writer Robert Gonzalez blew my mind with this point, “On the Black Album track 'Moment of Clarity,' Jay-Z contrasts his lyricism with that of Common and Talib Kweli” (both of whom rank higher than him, when it comes to the diversity of their vocabulary):

I dumbed down for my audience to double my dollars

They criticized me for it, yet they all yell “holla”

If skills sold, truth be told, I’d probably be

Lyrically Talib Kweli

Truthfully I wanna rhyme like Common Sense

But I did 5 mil - I ain’t been rhyming like Common since

I used a research methodology called token analysis to determine each artist’s vocabulary. Each word is counted once, so pimps, pimp, pimping, and pimpin are four unique words. To avoid issues with apostrophes (e.g., pimpin’ vs. pimpin), they’re removed from the dataset. It still isn’t perfect. Hip hop is full of slang that is hard to transcribe (e.g., shorty vs. shawty), compound words (e.g., king shit), featured vocalists, and repetitive choruses.

If you’re looking for more quantitative analysis of hip hop, check out Tahir Hemphill’s many foundational projects (and whose work initially inspired this analysis) and Martin Conner’s Rap Analysis.
