Why are animals used in English idioms?

Animals play an essential role in English idioms for various interrelated reasons. One of these factors is that animals often create vivid mental images that remain fixed in our minds better than any abstract concept. 

For instance, when someone says “busy as a bee,” we can easily picture a bee’s movements, which helps us better understand the concept of “industrious.” Certain animals are often associated with particular qualities, and this explains the prevalence of animal idioms. The key to the persistence of these expressions is their ease of recall.

How native speakers actually use animal idioms

These expressions are a part of everyday English conversations. However, they are not overused to the extent that they appear in every sentence. The native speakers incorporate them in the sentence when the situation demands. The expression comes spontaneously. It’s helpful to understand when and how to use them naturally.

  • Animal idioms for conversation. For example, instead of saying “I had a really busy day,” an individual could say “I was as busy as a bee today,” which is friendlier. 
  • Professional context. These phrases are used during team chats, coffee breaks, or casual meetings. Coworkers use them for small talk or to make a point, but do so in a casual, relatable way.
  • Social media and modern English. If you scroll through any platform where English is used, you’ll see how often animal-related idioms appear in captions, comments, and memes. People use idiomatic phrases to be witty, relatable.
  • Moderation usage. One essential thing to remember is that native speakers do not overuse idioms in their conversation. Using too many special phrases in a row may sound unnatural, exaggerated, or even humorous.

Animal idioms in everyday English are popular among fluent and native speakers because they make messages in WhatsApp and real-life conversations colorful, relatable when used properly. Further, you will learn about typical mistakes that take place when learning how to use idioms. 

Common learner mistakes with animal idioms

Using figurative phrases can make your language sound surprisingly natural, but they can also be some of the most difficult idioms to master. The reason is that they are so figurative and culturally specific that you can easily misunderstand their meaning or else.

Here are some common mistakes with animal idioms that language learners make with idioms involving animals, as well as how to avoid making them.

  • Using idioms in the wrong contexts

Some may seem friendly and casual, while others may seem offensive, condescending, or too casual. Using an informal phrase during a formal meeting or an offensive phrase during an emotionally charged conversation may result in an awkward moment.

Previous studies were a red herring.
Previous studies produced misleading conclusions.
  • Overusing idioms

Many learners think that using more popular idioms in everyday English in their speech will help them sound more fluent. However, the truth is, the more idioms you try to fit into a single conversation, the more unnatural the speech sounds.

Incorrect Correct

  • Mixing up similar idioms

Many animal-related idioms share a similar form, which leads to confusion. If you get them mixed up, the meaning of what you are saying may completely change. Instead of guessing what each idiom means based on the animal, look at the actual meaning of each.

Incorrect Correct
I feel like a black sheep at the new school.
I feel like a fish out of the water at the new school.
Don’t let the cat out of the bag about the argument — it is better to move on.
Let sleeping dogs lie — it is better to move on.

Students often struggle with these expressions by translating them literally, using them in inappropriate contexts, and overusing them in their own speech. Idioms are highly culturally and context-dependent expressions, and the best way to avoid them is to read examples and use phrases sparingly and appropriately.
