IELTS Writing for Russian speakers: How to Fix Run-on sentences and comma splices

Never join two full sentences with only a comma. Use a full stop, a semicolon, or a conjunction such as 'and', 'but' or 'because'. Check each sentence for one subject-verb core and clear punctuation.

Why this happens to Russian speakers

Long sentences feel advanced, but without correct joins they become run-ons. Punctuation is part of Grammatical Range and Accuracy, and frequent comma splices are a typical Band 6 error.

Why this affects Russian speakers: Russian has no articles, and its flexible word order and long sentences carry into English.

Articles and verb-tense choices (such as present perfect) are common errors.

A strength to build on: A strong grammar foundation and an analytical writing tradition help with logical structure.

Fix it in four steps

  1. Mark every sentence that has more than two verbs and check how its parts are joined.
  2. If two full sentences meet at a comma, change it to a full stop or add a conjunction.
  3. Break any sentence longer than about 30 words into two.
  4. Read the essay aloud and mark where you need to breathe, which is often where punctuation is missing.

Questions and answers

How can Russian speakers fix run-on sentences and comma splices?

Never join two full sentences with only a comma. Use a full stop, a semicolon, or a conjunction such as 'and', 'but' or 'because'. Check each sentence for one subject-verb core and clear punctuation. Articles and verb-tense choices (such as present perfect) are common errors.

How long does it take Russian speakers to fix run-on sentences and comma splices?

Most learners need one to two weeks. Focus on article and collocation drills in short daily blocks.

What is a comma splice?

Two complete sentences joined by only a comma. It is a common punctuation error and easy to fix with a full stop or conjunction.

Is a very long sentence ever a problem?

Yes, if it is hard to follow or poorly punctuated. Clear sentences of moderate length are safer than long, uncertain ones.

What does a good practice drill look like for Russian speakers?

Find ten long sentences in your old essays and rewrite each as two correct sentences or one correctly joined sentence. Focus on article and collocation drills in short daily blocks.

How can Russian speakers tell they have fixed run-on sentences and comma splices?

A punctuation check finds no comma splices in your last two essays.

What should Russian speakers know about their IELTS Writing target?

Russian-speaking candidates often have strong grammar knowledge and need targeted work on articles and natural word choice.

Should Russian speakers practise this on Task 1, Task 2 or both?

It shows up in both tasks. Fix it in Task 2 first, because Task 2 carries about twice the weight of Task 1, then check Task 1 with the same checklist. A strong grammar foundation and an analytical writing tradition help with logical structure.

Can an AI checker help Russian speakers with run-on sentences and comma splices?

An AI checker can show where this pattern appears in your own essay and which criterion it affects, which makes the fix concrete. It gives a practice estimate, not an official IELTS score, so use it to choose the next revision, rewrite, and check again. The first check on this site is free.
