The choice depends on your reason for learning it. If you are wanting to have more options in business, you need to know which languages are used around the world for whatever business you are in. Good worldwide languages at present - those that cover a lot of different territory - would be Spanish, French, Mandarin Chinese, Japanese, Russian, Arabic, and If you are learning it for pleasure, you might want to consider whether you want something easy or challenging.
For the easy choice, select a language related to your own mother tongue (for example, English-German-Dutch-Norwegian-Swedish-Danish would be one group; Spanish-French-Italian-Portuguese-Romanian would be another; Slavic and Semitic languages would form other groups). For a challenge, do the reverse and choose a language that is not related to your own. Some people even like to learn languages that few people know, in an attempt to help preserve languages that are dying out.
If you know a lot of native speakers of a particular language, you should learn that language. You will be able to practice speaking with them, so you would probably learn it far more easily. If you don't, then you could decide which based on how commonly spoken a language is, the ease of finding learning materials, the ease of learning that particular language, a country you would like to visit or economic value.
The most widely spoken languages are Mandarin, Spanish, Arabic and Bengali. Mandarin, Spanish and Arabic have a lot of economic value but Spanish is the only one that would be fairly easy to learn for an English speaker. Plus, you will find a huge amount of learning materials.
There are so many Spanish speaking countries to visit and so many Spanish speakers in the US. For those reasons, I would suggest Spanish.
Chinese because then you can teach it to me :).
If you know English, Spanish and Chinese, then you can speak to 88% of the world.
I suggest you German or Chinese/Japanese as these languages are in demand nowadays if look at it from a professional's point of view.
Spanish as it is easy to learn and used in a few parts of the States if you plan to visit there. It is also an interesting language to learn and you will find it an enjoyable process, as the grammar is fairly easy to grasp too. Plus you will find once you learn the language you'll no doubt want to try Spanish food, which is healthy and delicious!
Good luck and I wish you the best!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
