| What criteria are you using? ~320M French speakers globally (220M native, official language for 29 countries) ~559M Spanish speakers (~480M native, 20 countries) ~1.1B Mandarin speakers globally (a few countries, mother tongue in ~20 countries) ~1.5B English speakers globally (~400M native, official language for 67 countries) So for much of the world it seems pretty clearly English (& has been since WWII) and French is in the “second” tier competing with Spanish and Mandarin (probably just behind Spanish & Mandarin in terms of penetration lingua franca is about being the bridge language). |
