Member access
Sign in to your existing account or choose a subscription plan to unlock the complete BSL Sentence Builder and begin creating authentic British Sign Language sentences.
The BSL Sentence Builder is an interactive learning tool designed to help you understand authentic British Sign Language (BSL) grammar and sentence structure. Developed with Deaf signers, it enables learners to build natural BSL sentences, improve communication skills, and gain confidence through practical video-based examples.
A subscription gives you full access to our interactive BSL Sentence Builder, allowing you to practise real British Sign Language grammar whenever you want. Whether you are a beginner, student, teacher, interpreter, or organisation, our tools are designed to support your learning journey.
The BSL Sentence Builder supports anyone wanting to improve their British Sign Language skills. It is ideal for Deaf and hearing learners, families, interpreters, teachers, students, support workers, and organisations looking to develop better communication and accessibility.
When you have access to the builder, begin with a short everyday phrase. Watch the available sign videos and compare the sequence with the English phrase you entered. Repeat the example at a comfortable pace, paying attention to the visual demonstration as well as the words on screen.
Change one part of the phrase at a time so you can concentrate on a small amount of new vocabulary. If you cannot recognise an individual sign, look it up in the BSL dictionary before returning to the complete sentence.
Use the tool as a practice aid and bring questions to your tutor, particularly when a phrase depends on context. For guided study, explore the current BSL courses. The education library also offers other activities to use between lessons.
