The interactive Grammar of English (iGE) is a comprehensive introductory course in English grammar which takes you from the most basic elements to the most complex constructions. iGE is an authoritative guide to the structure of the English Language specifically designed for mobile devices to meet the needs of busy teachers and students. REAL ENGLISH, REAL GRAMMAR iGE uses lots of examples of real language taken from the 1M word ICE-GB Corpus, compiled and analysed at UCL and used by linguistics researchers across the world. Our examples of spoken and written English demonstrate that grammatical concepts apply to all uses of the English language, not just so-called 'Good' or 'Correct' English. LEARN FROM EXPERTS iGE is written by a team of linguists at University College London (UCL), independently ranked as one of the world's best Universities. The grammar you'll be learning is based on recent research and best practice in the field. Our grammatical analysis has been proven on over a million words of written and spoken English. The iGE course covers the same ground as a first year undergraduate course in Modern English Grammar. But that does not mean it is difficult to follow! We have written iGE to be accessible, with clear explanations, colourful notation and lots of examples. WHO IS iGE FOR? iGE is for everyone with an interest in the grammar of English. The course is is suitable for • anyone wishing to learn English or improve their English • students studying English language at secondary or high school • those studying English as a second or foreign language • teachers of the English language • undergraduate students of linguistics • students of English literature • journalists, civil servants and anyone interested in clear, plain English WHAT DO YOU GET? iGE contains: • A comprehensive course in grammar including: - word classes (nouns, determiners, verbs, etc.), - phrases, clauses and sentences, - grammatical functions (Subjects, Objects, etc.), - and many more topics along the way. Creating iGE was an exercise in miniaturisation. We cover the same range of topics found in a heavy grammar book, typically costing five times the price or more, and squeeze it into your device. We have simplified the presentation to make it easier to read, and exploited the capabilities of the device. • A complete grammatical glossary: a searchable A-Z of grammatical terms (see picture below). The interactive Grammar of English is extensively cross-referenced via the glossary. Grammatical terms are highlighted throughout the course with a dashed green underline (see below). Tap on one and you get the definition of the term, links to other related definitions, and a list of pages in the course explaining the term in more depth. • Many interactive exercises and quizzes to test yourself. Our exercises use hundreds of real English examples. You can try an exercise again to get new examples. Exercises can be timed, and for a real challenge, played against the clock.

This entertaining and educational matching game app helps you practice your English grammar and spelling in a fun way. Whether you need to brush up on parts of speech, conjugation or declination, tenses and types of sentences - no matter what you need, the various grammatical areas can be combined with each other and practiced. With one click, the appropriate themes are chosen, easy as pie, and you can start right away. Matching pairs must be found, either by purely assigning terms to the proper categories (funny = Adjectives | I would like to play = Futur 1) or as a concentration-enhancing matching game. THE GRAMMAR CHALLENGE HELPS YOU PRACTICE YOUR KNOWLEDGE IN A FUN WAY Both the number of card pairs and the number of players are, of course, variable. Depending on your wishes, the cards can be read aloud, and the length of time in which the cards are revealed is adjustable. The difficulty level of the app increases with the number of card pairs and the chosen area of grammar. It is aimed at all students who are not yet entirely comfortable in their use of grammatical terms or who want to practice for their next grammar lesson in a fun way. You can also work on improving your spelling. STRONG MOTIVATION TO LEARN GRAMMAR On your own in a race against time or against a challenging opponent - who will use the fewest number of moves to find the matching pairs? Who will collect the most stars and end up the winner in this grammatical duel? The beautiful visual presentation of the playing cards, the acoustic sounds of success, the pleasing voice that reads aloud, the game variations, the pedagogically sophisticated content and the strict limitations of only relevant content make this app a truly worthwhile learning aid. The Grammar Challenge makes learning grammar fun!

The idea was implemented by Jan Essig (www.janessig.com), a designer who has made a name for himself with his high-quality educational apps “Adventure Playground” and “Preschoolers ABC Playground” and has won numerous awards. The English voice recordings and translation were provided by Tom Harris (www.mrtomharris.com). The English grammar was advised on by Roger Griffin and Kate Griffin (www.kategriffin.info), who is a freelance copy writer and editor.
