With all its inconsistencies and irregularities, English is a particularly difficult language to learn after early childhood. However, the demand for English in this age of globalization is rising while the language is not getting any easier. Our Engram team collected the 20 most common English mistakes made by non-native speakers to help international English learners identify and solve these errors.

The most common mistakes by non-native speakers were found to be with articles and prepositions. Other notable common mistakes were with capitalization, verb tenses, idioms, subject-verb agreement, commas, run-on sentences, parallelism, word order, and formatting.

Consuming English content and listening to how native speakers speak are key to gaining new vocabulary and learning English grammar naturally, but not all English learners have the opportunity to have long interactions with native speakers or have time to watch thousands of hours of English media or read countless pages of English books. Engram’s list of common mistakes can help accelerate the learning process by pinpointing the biggest problems that non-native speakers struggle with.

On Engram's grammar checker, international English speakers can also input their English writing to check if their sentences sound natural and get immediate feedback. The immediate feedback and suggestions save time, as there is no need to hire a human proofreader or ask an acquaintance to check over the sentences.
