1. Chinese

Technically, Chinese is a "macro-language" that encompasses dozens of different dialects and forms that together have just short of 1.2 billion native speakers. In total there is 1197 million native speakers ( Mandarin having 848 million speakers ). Mandarin, is also the most widely spoken variety of Chinese with 70% of China's entire population .

As stated in the Oxford English Dictionary ( OED ), Chinese words have been recorded in English since the mid- 16th century, with early examples like tai chi ( year 1736 ), ginseng ( year 1634 ), yin and yang ( year 1671 ),  kumquat ( yer 1699 ), and feng shui ( year 1797 ).  To conclude, the earliest of all "loanwords" from the CHinese language, is lychee ( year 1588 ).

2. Spanish

Out of the 399 million Spanish speakers, 1/4 live in Mexico, while 41 million live in Colombia, 38.8 million in Argentina, 26.3 million in Venezuela, with 34.2 million in the United States, as in Spain ( 38. 4 million ).

Spanish "loanwords" in English are characterized by term from military and weaponry ( guerrilla, flotilla, armada, and machete ), animal names ( chinchilla, alligator, cockroach, iguana), and lastly, the terms from food and drink ( potato, banana, anchovy, vanilla).

3. English

The English language's 335 million native speakers include exactly 225 million in the United States, 55 million in the United Kingdom, 19 million in Canada, 15 million in Australia, and just short of 4 million in New Zealand, all according to Ethnologue. Even though English is not #1 in the world for languages, it is one of the world's most widespread languages, with it's mother-tongue speakers recorded in 101 separate countries and territories worldwide, 94 classed as an official language. Concluding, if the number of people who use English as their second language were included, the global total of English speakers would rise over 1 billion, easily!

4. Hindi

Most of the world's 260 million native Hindi speakers are located in Nepal and India, while an estimated 120 million more people in India use Hindi as their second language. Hindi is also the most widely spoken language of India! 

Just like all the other Indian languages, a lot of Hindi loanwords found in English were adopted during the British Raj in the 19th and early 20th centuries. But long before that, rupee ( year 1612 ), guru ( year 1613 ), pilau ( year 1609 ), myna ( year 1620 ), and juggernaut ( year 1638 ) had appeared.

5. Arabic

For starters, Arabic is just like the Chinese language in the sense that it is a macro-language, or a language that consists of many different dialogs. The cause is simply because the Arabic language has 242 million native speakers that are spread worldwide to 60 different countries. Also, because of the spread, Arabic speakers use a range of different forms and varieties.

Moving on, the very first Arabic "loanwords" in English date from the 14th century, such as these rather rare words, alkanet, a type of dye ( year 1343 ), and hardun, an Egyptian agama lizard ( year 1398 ). Other than the rare words, there are the more familiar words, like hashish ( year 1598 ), sheikh ( year 1577 ), and finally, kebab ( year 1698 ).

6. Portuguese

The Portuguese language has 203 million speakers, but ironically, the population of Portugal is just under 11 million. As a result, the global "Lusophone" population is being enormously boosted by Brazil's 187 million. 

Over all, both the Portuguese and Spanish "loanwords" are some times tricky to differentiate due to the many similarities between them. But, according to the OED, Portuguese is responsible for the words marmalade ( year 1480 ), pagoda ( year 1582 ), commando ( year 1791 ), cuspidor ( year 1779 ), and piranha ( year 1710 ).

7. Bengali

Surprisingly, after Hindi, Bengali happens to be the 2nd most widely spoken language of India, with enough over 82 million speakers, and 189 million speakers in total. Moving on, the largest native Bengali population in the world is located in Bangladesh, where 206 million speakers use Bengali as their main/ first language.

The amount of words adopted in English is rather small, with only the exact amount of 47 instances, recorded in the OED. For instance, some are jute ( year 2746 ), almirah , a free-standing cupboard ( year 1788 ), and jampan, a type of sedan chair ( year 1828 ).
