Easiest Critical Languages to Learn

[LevelUP]

Tagalog has the same alphabet as Spanish and uses a lot of Spanish words.  Its words and spelling are similar to English.


There's a debate as to what it means to be fluent. 
#1 Fluent enough to get by as a tourist?
#2 Fluent enough to pass a DELE Examination? (Spanish achieving a B1/B2 rating)

Does fluency mean I know:
#1 % of the language words
#2 % of the sentences I can understand the important context?
#3 Overall ability to read, speak and understand the language measured by an exam or personal experience?

For example, if I say, "Today I repaired the red car."  

If I knew 5 out 6 words (83%) of that sentence, one might say, "oh boy, that's great" however if I had no idea what the word "repaired" meant, I would lose context of what the sentence meant.  On the other hand, if the only word in that sentence I didn't know were the word "red," I would still understand the context of the sentence clearly.  

In other words, there is a massive difference between the words repaired, washed, drove, stole, etc.
