Is it dyslexia, or is it the second language?

Every international classroom knows this question

A bright, curious child who keeps up in everything, except reading and spelling. The teacher wonders whether it is simply the second language settling in. The parents see something deeper. Assessment is designed for monolingual children, so the answer keeps sliding out of reach. And while the adults hesitate, the child waits. Falls further behind. And slowly starts to believe something that is not true: that they are not smart.

Lexilogy was built for exactly this child

Not by working around the question, but by going underneath it:

strengthening the processes that reading and spelling are built on, in whichever language the child needs. First the strongest language. Then the second.

Not more practice. Learning to see into words

Lexi-PRO is not a practice app. No word lists to memorise, no drills on top of a shaky foundation. It is a structured intervention that repairs the foundation itself, in three layers, always in this order.

Where other programmes stop at sounds and spelling rules, Lexi-PRO goes further. A child learns that a word is not a string of letters to memorise, but a logical construction in which sound, meaning and word parts belong together. That is the difference between compensating and understanding. 

For ages 8 to 18 · At home or at school · On a computer or laptop

33% improvement. Measured. Published

The Lexilogy method has been evaluated in peer-reviewed research, published in the European Journal of Special Needs Education. The study was conducted with the Greek version of the programme, in collaboration with the University of Amsterdam and the University of York:

an average improvement of 33% in both reading and spelling

among children who completed the full programme

The English, Dutch and Greek versions are built on exactly the same foundation: phonological awareness first, then morphological awareness, then automatisation. Three languages, one method.

My goal: to turn your child into a lexilogist

Lexilogy is not in the dictionary. The name came from a dear friend, a writer, who watched me take words apart for years to see how they were built. She gave that work its name. 

Lexis means word. Logy means knowledge, the craft of

A lexilogist sees through words to the bottom:

how they sound, how they are built, where they come from

And that is what I want your child to become. Not a child who memorises lists, but a child who sees into words. I did the groundwork myself, across three languages. I began with Greek, a language so transparent that its structure is almost visible. Then English. Then Dutch. Three languages taken apart from the inside, and that is why I see what specialists who know only one language cannot see.
