[|AI|] The most popular second languages to learn for English speakers are Spanish, French, and Italian, although from a utility perspective the most widely spoken languages aside from English are Mandarin and Hindi. You might choose a second language to learn based on upcoming travel plans or for work reasons, or purely for fun!
