For example, in English, we take medicine. We don't eat it, but in Korean, Japanese, Chinese, or Arabic, they use the same verb for eating.
Sure, a native speaker will understand what you mean when you say you need to eat some medicine but they will probably think of something like this:
You're basically trying to learn collocations, which is basically words that often appear together. For example:
take + medicine
juicy + steak
cell + phone
pots + pans
cats + dogs
If you're using a word that is unfamiliar, my best piece of advice is to look up collocations in a corpus.
A corpus is basically a large collection of text. My favorite corpus to use is the COCA (the Corpus of Contemporary American English). You can type in a word, and then click "collocates" and insert an asterisk (*) to look for any word, and basically, it will look for the most common words that show up with that word.
Since it's Memorial Day, let's look up barbecue and find out what it collocates with (the number in parentheses is the frequency):
1. sauce (539)
2. grill (151)
3. chicken (84)
4. pork (80)
5. backyard (71)
6. cup (70)
7. pit (64)
8. Texas (63)
9. grills (60)
10. joint (55)
As can be seen, the highest one is sauce, and anyone who has ever been to a barbecue would be surprised NOT to find barbecue sauce.
You also learn something about the culture of American English--notice the most common location associated with barbecue is backyard. When I lived in South Korea, barbecues typically took place in a public park, which isn't surprising considering the fact that so many live in high-rise apartment buildings, so they don't have a backyard to barbecue in!
You might learn some other interesting things along the way--like the fact that joint is more popular than restaurant (or maybe you didn't realize joint referred to things other than knees, ankles, elbows, and hips).
Anyway, take a look at my Links section and look under Corpora (corpora = plural of corpus) to find more searchable corpora.
Have a good one, and good luck out there!
