By contrast, languages such as Finnish and Korean have very regular spelling systems; rules govern the way words are written, with few exceptions. Finnish also has the added bonus of a nearly one-to-one correspondence between sounds and letters, meaning fewer rules to learn. So after Finnish children learn their alphabet, learning to read is pretty straightforward—they can read well within three months of starting formal learning, Bell says. And it’s not just Finnish- and Korean-speaking children who are at a significant advantage: A 2003 study found that English-speaking children typically needed about three years to master the basics of reading and writing, whereas their counterparts in most European countries needed a year or less.
