Classifications of consonants

When to use abstract nouns—and when not to. Abstract nouns are perfectly at home in philosophical, existential, and ideological conversations—it’s hard to discuss these matters without them. Likewise, discussions about emotions and feelings usually contain abstract nouns, especially when feelings are ongoing or constant. 
The trouble with abstract nouns, though, is that they tend to be vague. Because we can’t perceive them physically, everyone has their own idea about what they are. Just as “beauty is in the eye of the beholder,” the word beauty is interpreted differently by each “beholder.” 
For this reason, good writing often involves concrete examples sprinkled in with your abstract nouns to anchor the discussion in reality. Concrete examples illustrate our points and encourage readers to see things our way, rather than their own way by default. For example, if you were writing an essay about the importance of choosing a career (abstract noun), you’d do well to mention specific careers like doctor, mechanic, or proofreader (concrete nouns). Abstract nouns and their rules can be a lot to absorb. Hopefully with our guide, you have a firmer understandding—and are on your way to writing about them with ease. 
Abstract or Concrete? It Could Be Ambiguous. It is not always easy to differentiate between an abstract noun and a concrete noun, and it is not unusual for students to argue over whether a noun is abstract or concrete. For example, "laughter" is often cited as an abstract noun, but "laughter" can be heard, which would make it a concrete noun. We would agree that "laughter" is a concrete noun, but what about "love," "work," and "result"? It is fairly easy to make cases for these being concrete nouns, but they are classified as abstract nouns. Be aware that the distinction between abstract noun and concrete noun is sometimes blurry. Also, be aware that classifying a noun as abstract or concrete may depend on context or even the classifier's definition of perceivable. Look at these two examples:

• 
  Working for Disney was a childhood dream come true. (American actress Brittany Curran) (In this context, "dream" is an abstract noun with a meaning similar to "hope.")
  
• 
  When I was a little kid, I used to have a vivid recurring dream about Captain Hook. (American actress Cristin Milioti) (In this context, "dream" does not mean "hope." Here, "dream" could be classified as a concrete noun, especially if you think a dream is perceived via your senses.)
