As you can see from [this map][1] on the Wals.info site, there are many. More explanations on the [main page][2]. 

After a quick search I did, it surprised me to see some languages on this list that seemed to use the same word for one and the indefinite article, such as Dutch. I might be wrong, it seems, so you might want to look more in depth for the ones you want to study more.

Anyway, they are **102**. I'll list them below for ease of reference alphabetically and ordered according to the continent.

><sup>**Note**: I removed the false positives or the ones that arose as not fitting.</sup>
