Free is good, right? Many lazy students like to use free online dictionaries to learn English. This is a good way to harm yourself by memorizing mistakes.
Here is a page from a well-known online English-Chinese dictionary:
Is this so-called "dictionary" reliable? Notice: It's not really a dictionary. It's only a glossary. Please think: If it's free, who will check for mistakes? If you find a mistake, can you complain? Can you get your money back?
Let's check COCA for sentences with lover:
Did you notice how lover collocates with attack, beat up, kill, murder, shoot? Is that what people do to 情侶?Please remember this English proverb: "You get what you pay for" (一分錢一分貨)! There are many excellent English-English learner's dictionaries to help you learn English. Spend a little money and time to learn how to use them. Please don't waste your time with unreliable bilingual dictionaries (不可靠的雙語字典).
