Enough has been said about cohesion. Let’s talk about coherence.

Coherence and cohesion

Coherence is the logical unity of ideas. Cohesion is the linguistic ways of achieving that. I’ll give a couple of absurd examples to illustrate the concepts:

Pure cohesion: "I like apples. This leads to my passion for writing. Additionally, hedgehogs are cute." The cohesion is there - this leads to and additionally. But the coherence isn’t - there is zero connection between ideas.

Pure coherence: "I like apples. I find pears delicious." The ideas are connected - I talk about two types of food I like. But there is no linguistic marker to unite them, so they look isolated.

Ideally, coherence and cohesion must work together: "I like apples. I also find pears delicious."

Cohesion is easy because it’s noticeable - you have an actual word or phrase that will unite your ideas into one whole. But cohesion must support coherence, not substitute it. If your ideas are not logically connected on the level of ideas, no cohesion will save them. If you add “additionally” to your sentence, it doesn’t mean the ideas are suddenly connected. 

So how do you achieve or check for coherence?

Before I share my solution, let’s conduct a small experiment. Look at this sentence, pause for a moment and think what sentence might go next.
  • This world is changing rapidly, but not everyone is ready or able to accept the changes.
Now look at what the student actually wrote.
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. However, effective communication and understanding can be useful tools in breaking barriers.
The cohesion - however - is there. The coherence isn’t - the ideas are totally disconnected.

How do you make sure your ideas are connected on the level of ideas? My solution is invisible questions. For example:
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. (Who isn’t?)
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. (What changes?)
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. (Why aren’t they ready or able?)
After you’ve built those invisible bridges in your head, albeit in draft form, you are ready to add cohesion. For example:
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. (Who isn’t?) Older people, for example, find it hard to …
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. (What changes?) These include new technologies and new social norms which …
  • This world is changing rapidly, but not everyone is ready or able to accept the changes. (Why aren’t they ready or able?) This can happen because people become less flexible with age.
These invisible questions will help you link ideas on the level of ideas and then choose appropriate cohesive devices, thus helping you create a completely coherent and cohesive essay. You need to choose the questions wisely because each question will lead you further and further in a particular direction. Make sure it's the direction you need. 

Some questions will help you identify what’s missing and add it. Let’s go back to my student’s example:
  • “This world is changing rapidly, but not everyone is ready or able to accept the changes.” The missing question is, “What is the result of this?” So the missing sentence is probably, “This leads to misunderstanding and conflict between people of different generations.” And then we have this invisible question “How can this misunderstanding be resolved?” and our original sentence, “However, any such misunderstanding can be resolved with open and effective communication.”
With the help of the invisible question we identified what was missing, added it, and ended up with a more coherent paragraph:
  • “This world is changing rapidly, but not everyone is ready or able to accept the changes. This leads to misunderstanding and conflict between people of different generations. However, any such misunderstanding can be resolved with open and effective communication.”
Cohesion has been discussed ad nauseum - everyone and their mother knows all those cohesive devices. But coherence is more elusive - when you write, everything seems connected to you. How do you notice this lack of coherence? How do you notice that your ideas seem disconnected? I hope it will be easier with this post.

How to tame your IELTS pie charts

Image
IELTS line graphs are easy to tame - you just go chronologically, so the description doesn't get out of hand. Information in pie charts, however, can be hard to organize because there are different directions you can go in. In this post, I want to share two IELTS pie chart answers I wrote for the same task. The task is from Cambridge IELTS 11 . The introduction and the overview are the same. As you read, pay attention to the organization and try to decide which description works better. ✼✼✼ Introduction  The pie charts compare the percentage of British students of one English university who knew foreign languages in 2000 and 2010. Main Body Version 1 The percentage of students in three groups grew. Speakers of Spanish formed the largest share in both years, rising by 5% from 30% to 35%. The increase was the same in the “Another language” and “Two other languages” groups. In 2010, the former amounted to 20%, while the latter comprised 15%, making up the second and third largest prop...

My Fulbright application or a teachable moment on essay writing

Image
I did it one day before the deadline. I submitted my Fulbright application on 30 May 2014. Now, 14 months later, I am going to the USA as a proud Fulbrighter! The program I am participating in is called Foreign Language Teaching Assistant or FLTA for short. As a participant of this program I will be teaching Russian and studying at an American university for an academic year. When my students heard the news, they asked, “What did it take to get this grant?” I replied, “Well, there were several stages. First, I had to write a lot of text. Then, I … .” And one student said, “I am curious to read what you wrote.” I suppose many are, so I am going to let you in on one of my application essays. One of the essays I wrote is called “Objectives and motivations.” What I wrote is too long to upload here (1274 words, no less!), so I am only going to share my introduction and conclusion . Oh, and I see a teachable moment here, which I just can’t help using. Introduction "Albe...

C2 Proficiency. Writing Task 2. Review (of a film I haven’t seen).

Image
I keep writing like crazy because I am preparing for the C2 Proficiency test (fka CPE). In my previous post, I shared my Writing Part 2 article . In this post, I want to share a review I wrote about a movie I haven't seen and give some insights into handling an unfortunate task. Task A film magazine has invited readers to submit reviews of films which are set in the future, but deal with themes relevant to today’s world, such as our relationship with technology or environmental problems. You decide to submit a review briefly describing such a film and explaining why its themes are relevant today. You should also consider how important it is for films set in the future to say something about contemporary society.   ( Cambridge English Proficiency 2 , Test 2, Question 4). This is a really unfortunate task for me because I watch very few movies, maybe 3 a year. But as I read it, I imagined myself sitting in the exam room not wanting to fail, so I had to come up with somethin...

Top 8 mistakes Russian learners of English actually make

Image
Due to the nature of my job, every once in a while I stumble upon an article about N most common mistakes that learners of English make. I look at them and go, “Who makes these mistakes? Russians certainly don’t.” (For example, Russians don’t confuse your and you’re .) In this post, I want to talk about 8 common mistakes Russian learners actually make. These mistakes persist on different levels, but are not usually addressed in EFL course books. The list is based on my personal teaching experience. The order is random. 1. I with I often ask students “What did you do at the weekend?” and what I hear is “ I with my friends went to the cinema. ” The right way to say something like this is “ My friends and I went to the cinema ,” or “ I went to the cinema with my friends .” In English, the word order is “subject+verb” and prepositional phrases can’t go in the middle. 2. How to say When students don’t know how to say something, they ask me or murmur to themselves “ How t...
