Six Key Areas in English a Writer Needs to Pay Attention to

Below are six key areas in English every writer needs to pay attention to:

1. Subject-verb agreement/Concord

One defining characteristic of a good writer is one who has command of subject-verb agreement, not necessarily one who flaunts "big" words. Start from the basics – they are, she is, we were, etc. – and build on them. Get a good grammar book and learn the rules of concord, or click here to learn the rules of concord. The life of good writing depends on this!

2. Tenses

Tenses tell the times that certain events happened. As a good user or writer of the English language, you should be able to describe past, present, and future events in their appropriate tenses. There are several quality grammar books you can master tense and aspects from.

3. Punctuation

A good writer knows that punctuation is as important as the brakes, clutches, and accelerators of cars. You miss their right usages and you risk your life. Know where to place commas, periods, apostrophes, hyphens, colons, etc. A misplacement of these marks would result in different meanings and structures.

READ: How punctuation marks affect your writing

4. Vocabulary

To be able to express yourself very well in written language, one needs a rich vocabulary. A “rich vocabulary” does not necessarily mean a plethora of "big" words. By “rich vocabulary,” we mean the appropriate words or phrases to describe thoughts, actions, people, situations, etc.

5. Idioms

Idioms add colour and condiments to one's language. They make one's writing sweet and pleasant to hear. Idioms transform ordinary writing into an excellent one. Get a stash of idioms and use it in your writing. With time, these idioms will form part of your style of writing.

READ: How to be a good writer

6. Spelling

Clarity in the spelling of words eases the understanding of writings. Once you miss the spelling of a word, it ceases to be the word you intended. Every writer should note this. If you can't spell a word, don't write it. You can always double check the correct spelling of words from a trusted dictionary.

5 Simple Language Learning Strategies Guaranteed To Help You

If you are one who is interested in learning new languages without getting freaked out by the difficulties faced in the language learning process, then you are at the right place!

You may have observed that someone around you has mastered common Spanish words in a couple of weeks and someone has taken several months only to talk under breath ‘Buenos días’ or ‘Hola’. Making clever choices and using the right strategies can make your journey of learning a new language a lot easier and definitely enjoyable.

Here you will find five simple language learning strategies that will help you to overcome your struggles with learning a language and make it super fun for you.

1. Keep Your Self-Motivation High

Self-motivation is essential for learning a new language. In other words, self-motivation is the key to learn anything new.Source of motivation for learning a language can be anything like your dream to get admission in a foreign university, your wish to communicate with your friend in his/her native language or whatsoever.

You can make your motivation stronger by associating it with your hobbies. If you are into listening to songs or reading books than listen or read in the language you are learning.

2. Set Realistic Goals
Setting realistic and achievable short term goals is also crucial to be successful in learning a new language. Make it clear in your mind what you want to learn and make realistic decisions about how much time you can give to your language learning process on a daily basis. Afterwards, stick to your decision!

Set goals of learning a few words or phrases on a daily basis. Give yourself a task to watch a movie or read a small article once a week in that particular language which you want to learn and try to comprehend it. If you really want to learn a language, then be your guard yourself.  Ensure that you exert all your energy to master and honestly fulfil the daily tasks regularly.

3. Learn To Pronounce Words Correctly
Many people fail in the language learning process because they do not focus on pronunciation. They want to learn a new language but are not ready to listen. In order to speak in a new language, you need to learn how words sound. If you wish to speak commonly used words more like a native speaker, then you should first pay attention to the pronunciation of these words. You can listen to the pronunciation of various words or phrases online.

If you are watching a movie, pay close attention to what is being said. While listening to the songs, you may actively listen to the lyrics in order to improve your speaking skills.

4. Focus on What’s Most Useful for You

To make your learning process more successful, identify what is the purpose and why you want to learn a new language. For example, if you want to communicate with your Spanish friend, then you only need to learn common words or phrases. In such a case, there is no need to learn the technical side of the language.

But if you want to read an academic book or article, you can have an in-depth knowledge of the language which needs a lot more effort and practice.

5. Take out Time To Practice

Taking out time to practice a language seems more like a chore but you can make it more fun by communicating with a native speaker over social media. You can participate in online challenges to check your progress in a new language or send texts to your friends using the newly learned words.
