প্রতিটি বাক্যে কর্তা ও ক্রিয়া লাগে। মৌলিক গঠন এবং দুটি ধারণা সঠিকভাবে যুক্ত করার নিয়ম শিখুন।

By the end of this lesson you can

  • Find the subject and main verb in a sentence
  • Use the five basic sentence patterns
  • Join two complete ideas without a comma splice

Subject + verb is the core

A complete English sentence has at least a subject (who or what) and a finite verb (what they do or are). "Prices rose." is complete. "Because prices rose." is not: it is only part of a sentence.

Most sentences follow one of five patterns: subject + verb (Prices rose), subject + verb + object (The city built a bridge), subject + verb + complement (The plan was expensive), subject + verb + object + object (The council gave residents a choice), and subject + verb + object + complement (Many people find the city noisy).

Joining two ideas

A comma alone cannot join two complete sentences. "Public transport is cheap, many people still drive." is a comma splice, a very common error in IELTS Writing.

Fix it in one of three ways: a full stop ("…cheap. Many people…"), a linking word ("…cheap, but many people…"), or a subordinating word ("Although public transport is cheap, many people still drive.").

From fragment to sentence

Fragment: Because the population is growing.

Sentence: Because the population is growing, cities need more housing.

Comma splice: Housing is expensive, young people live with their parents.

Fixed: Housing is expensive, so many young people live with their parents.

Each fixed version has a main clause with its own subject and verb.
