A personal spelling dictionary, being a collection of a single learner’s regularly misspelled words, is tailored to the individual and can be expanded with new entries that the learner does not know how to spell or contracted when the learner had mastered the words. Learners also use the personal spelling dictionary more than electronic spellcheckers, and additions can be easily made to better enhance it as a learning tool as it can include things like rules for writing and proper nouns, which are not included in electronic spellcheckers. Studies also suggest that personal spelling dictionaries are better tools for learners to improve their spelling as compared to trying to memorize words that are unrelated from lists or books.
