French would be a fun language, but is extremely hard which all the weird sounds you have to learn for certain letters. Spanish is extremely common, but it differs in where you live. As for me, living in the South where the French were means that in high school and middle school I had to learn French. As for me, I had chosen to learn Yiddish, Swedish, German, Irish and Arabic.
Also, Google Translate will fail you.... It said "Bonjour" meant computer. Bonjour- computer. Really, Google? Really?
Leraning languages took up 5 years of my life, but it is fun to be able to help people communicate.
