To learn more languages in DnD 5e, you must receive training from an instructor for 10 workweeks, reduced by a number equal to your Intelligence modifier. This costs 25 gp per workweek.

So, if you have a +1 Intelligence modifier, it would take 9 workweeks (45 days) and 225 gp to learn a new language.

A character must spend at least 8 hours each workday committed to learning the language for that day to “count” toward their training time. However, the days need not be consecutive. You can still go on adventures between your Abyssal study sessions.

You can also get the Prodigy feat as a Half-Elf, Half-Orc, or Human, granting +1 language, +1 tool proficiency, +1 skill proficiency, and +1 Expertise.
