Read full description

An English verb forms dictionary for Thai learners. Every verb shows its three forms: V1 (base form), V2 (past simple) and V3 (past participle). Most verbs just add -ed, but irregular verbs change in their own way and have to be learned one by one. This app has more than 5,800 verbs with Thai meanings, for students, O-NET and TOEIC test takers, and anyone who wants to write English correctly. Explanations are in Thai. What you can do • Type a verb in any form and see V1, V2 and V3 together with the Thai meaning • Listen to the English pronunciation and practise saying it • Save verbs you have not learned yet and review them on day 1, 3, 7 and 14, with a word of the day reminder • Verb games: multiple choice, picture guessing, matching, guessing the word from its meaning, and unscrambling letters • Vocab cards in flashcard, test, spelling, matching and unscramble modes • Quizzes and tests with instant scores, so you can see what to review • Articles on verb forms and English grammar from WordyGuru, inside the app • Share a verb as an image to LINE or social media, or copy it • Adjust the text size, and switch to the dark theme at night • Verbs and articles you have opened can be read again without internet (the first view needs a connection); can't find a verb? Ask the team to add it Practise a few verbs every day until they stick. The content is the same as wordyguru.com and is updated continually. Free to use, with ads. Developed by Wordy Guru
