While it may seem like an exercise in memorizing, spelling proficiency, especially in English, is largely a function of learning the patterns in which letters occur in the vernacular. Instead of something you can sit down and memorize in one straight cramming session, spelling is a skill that you develop increasingly over time.
In acquiring a strong grasp of spelling ability in any language, whether English, French or some other, being a wide reader of materials in the vernacular helps. Spelling skills are usually tied in directly with reading ability. The better your reading comprehension gets, the more proficient of a speller you usually become. Simply put, the greater variety of words you encounter, the more extensive your familiarity with the spelling requirements of that particular language becomes.
Similarly, extensive writing using unfamiliar words can facilitate the same gains. Language software tools for translation, spellcheck and grammar correction are usually your best ally when trying to develop spelling ability. Since spelling skills are developmental, having a good software constantly available to assist you during your writing efforts will help you “connect the dots” when it comes to mastering letter patterns in any language. Just make sure to set the software to alert you to errors, instead of automatically correcting, so you can see what you’re doing wrong and adjust accordingly.
Spelling isn’t a difficult skill to develop. However, it does take consistent effort on your part – both reading, writing and employing the proper tools – to effectively integrate it into your skillset.
