so you can use "difficult" to say that something is hard to do, you could also say it's just hard but lots of people say difficult instead because it's more specific. examples: "Learning a new language can be quite difficult"

It is a matter of preference. They are used interchangeably. However, I will mention this also...the word hard can also refer to things that are physically hard such as wood, rocks, and solid items. It may also be used to show force. Examples: He hit me very hard on the head. The table is hard and made from sturdy wood. So you can use hard to describe problems or difficult things... And you can use difficult also. Hope this helps you—best wishes :)

"Difficult" means only one thing: requiring a great deal of effort or skill. "The test was difficult." "Hard" means two things: the same thing as difficult, but also: solid, firm, not easily broken or bent. "The test was hard." and "The chair I sat in while taking the test was hard." Rocks, unpadded chairs, blocks of ice and overcooked eggs are hard. Tests, work, times, and decisions all can be difficult: you can also say they are hard.

"Hard" can be used as an adverb or adjective in almost any situation, while "difficult" is generally used only for actions. For example, you would never say "the rock is difficult". You would always say, "the rock is hard". On the other hand, you could say either, "the lesson was hard" or "the lesson was difficult". Try going through these examples: 1. The car was _____ to drive. 2. After lifting weights, the muscles in my arms were _____. 3. It was ______ to see the truth after listening to both people. 4. I want to learn Cantonese, but the language is too _____. 5. How was your daughter's chicken curry? "I found it _____ to eat, but I did not want to discourage her." 6. After the eggs were boiled, they were ______. Caution! Use of the word "hard" can sometimes have a sexual connotation and may be considered very vulgar in some conversations. (It refers to a person being sexually excited. Very common slang.) Good luck! Greg F.
