How to play Complete the Sentence
Read the sentence with a blank space and type the missing word or phrase. Some exercises accept multiple correct answers — the system will accept any valid completion. Press Enter or click Check to confirm each answer.
A running score tracks your progress through the exercise. If you answer incorrectly, the correct answer is shown so you can learn from the error before moving to the next sentence.
Why Complete the Sentence improves your English
Active recall — retrieving a word from memory rather than recognising it from options — is one of the most effective techniques in learning science. Unlike multiple choice, fill-in-the-blank forces your brain to generate the answer independently, which creates stronger, more durable memory traces.
Context is everything in language learning. Seeing a word in a complete sentence teaches you not just the word's meaning but its collocations, register, and grammatical behaviour — all at once. This mirrors the way native speakers naturally acquire vocabulary.
Study tip: If you get an answer wrong, don't just move on. Read the full sentence again with the correct word in place, say it aloud, and visualise using the word in your own sentence. This three-step reinforcement greatly improves retention.
Types of gaps in sentence completion
- Missing verb form: choosing the correct tense or aspect (was/were, has/have gone).
- Missing preposition: selecting the right preposition (interested in, good at).
- Missing vocabulary word: choosing the correct word from your known vocabulary.
- Missing article: deciding whether a/an/the or no article is needed.
- Missing connector: linking ideas with however, although, therefore, etc.
Tips for Complete the Sentence success
- Read the whole sentence first: The words before and after the gap give strong clues about meaning and grammar.
- Say it aloud: Your ear will often catch a wrong answer that your eye accepts.
- Check verb agreement: Singular/plural and tense consistency are the most common mistakes.
- Learn from feedback: Study wrong answers carefully — understanding why you erred prevents the same mistake.
