When learning a new language like English, understanding grammar can seem daunting. All the small and more in-depth rules form the structure of the language and are not always easy to grasp, at least at first. However, understanding grammar is essential for effective communication, and the skill can unlock many doors. Want to learn more? Here are 10 reasons why grammar is essential.
1. Enhancing Communication Skills
Communication skills help you out in almost every aspect of life. Whether making new friends, interviewing for a job, forming romantic relationships, or engaging in group activities, communicating well means people will understand you better, and vice versa.
Grammar is essential to this, as it brings structure to the words you speak or write.
2. Building Professional Credibility
When trying to build professional credibility, following grammar rules is enormously helpful. With well-written text that follows all the rules, you show you pay attention to detail and have intelligence. Using correct grammar will allow you to communicate better with other professionals, leading to better chances of climbing the ladder.
3. Boosting Academic Success
A huge part of academia is writing, meaning you must follow the English writing rules. Even a well-researched essay will not score as well if the writing doesn’t follow the correct grammar rules, whether that’s proper comma placement or using the correct pronouns. So, if you want to excel in your academic classes, getting to grips with grammar is a must.
4. Improving Writing Clarity
When it comes to good communication, clarity is key. It helps to demonstrate your exact thoughts and ideas in as few words as possible, and in such a way that the reader completely understands your viewpoint. With correct grammar, this is far more possible.
5. Strengthening Reading Comprehension
Do you ever find that reading long and complex texts leaves you scratching your head, unable to unravel the jumble of words? While one part of that may be due to a small vocabulary, it could also be because you don’t fully understand all grammatical rules.
Understanding English grammar allows you to decode even the most complicated sentences. You’ll find it easier to interpret meaning,
6. Supporting Language Learning
When learning a language, throwing yourself into the various words, phrases, and sentences you need to know is tempting. After all, knowing how to say, “how are you?” and “where is the bathroom?” is an essential step! However, if you want to go beyond the barest basics of a language, you must also dive into grammatical rules.
When you understand the grammar of a language like English, you will find the overall learning process easier. Things like sentence structures and the use of pronouns will start to fall into place and support your journey towards becoming fluent.
7. Facilitating Career Advancement
If you want to advance in any career, knowing grammar is key.
One reason for this is that expressing yourself clearly in writing is a way of gaining a better reputation. As previously mentioned, it builds more credibility and makes you appear more professional, and this can facilitate climbing the career ladder.
On top of that, the effective communication from understanding grammar can help you achieve career success. If you can write efficiently and communicate well, you are more likely to make stronger professional relationships and, in turn, advance in your career.
8. Promoting Effective Social Interactions
Interacting socially is a large part of being a person! Whether hanging with new friends, joining a weekly club, or simply conversing with a shopkeeper, knowing grammatical rules will help you engage in more meaningful social interactions.
Plus, many social interactions occur online where the written word is essential. Using correct grammar when conversing via email or instant messenger means the receiver will better understand what you are saying. It’s all about crystal-clear clarity.
9. Saving Time
The modern world is fast-paced, so there’s a great importance placed on the ability to save time. One way to save time in both your professional and social life is to know the right grammar rules to communicate more effectively.
Think about it – if you understand all the important grammar rules, you are more likely to communicate succinctly. You won’t have to have an overly long conversation or engage in too many email threads; instead, you can get straight to the point. It is especially useful in a business environment when you want to articulate your thoughts to a group of people quickly.
10. Avoiding Misunderstandings
Misunderstandings happen all the time, but they are even more frequent when you do not understand the exact rules of a language. The last thing you want is for someone to misinterpret what you say, which could lead to some sticky situations. The way to avoid that? By knowing English grammar inside and out. This is because you will speak more clearly, eliminating the risk of another person not understanding what you meant.
The Most Important Grammar Rules to Understand
You now know just how essential grammar is to communication. So, which ones should you start with? Work your way through learning the following grammar rules to gain a better grasp of the English language.
- Active vs. Passive Voice
- Use of Pronouns
- Comma Placement
- Avoiding Double Negatives
- Sentence structures
- Use of Conjunctions
- Consistent Use of Tense
- Capitalisation
- Use of Articles
- Subject-Verb Agreement
Working through each rule slowly and practising using the rules in sentences helps with learning.
