How Reading Works
When we read, we reuse the speech part of the brain. The eyes see the word, the speech system “hears” it silently, and the meaning system interprets it. With practice, the brain builds fast links between these systems so reading feels natural and automatic.
Fluent reading does not mean decoding a word every time. Instead, words become sightwords: one object in memory that combines shape, sound, and meaning. Once a word becomes a sightword, recognition is instant and understanding is easy.
Fluent reading is reading at the speed we speak—about 100 words per minute—while understanding what we read. At this speed, there is no time to apply rules or work through letters one by one. We need to see a word’s shape and instantly know its sound and meaning.
When you meet a new word in
A sightword is a word you can read instantly without sounding it out. You recognise its whole shape and immediately know its sound and meaning. This means a sightword is stored as one object in memory—not as separate letters—so it places almost no strain on memory while you read.
English has more sounds than letters, plus silent letters and shifting stress. Rules help sometimes, but there are many rules, many exceptions, and they often produce wrong sounds. Trying rules, trying to remember exceptions, or trying out different sounds of the word mid‑sentence is slow and breaks understanding. Worse, if the first attempt is wrong, that wrong sound can get in the way of learning the right one later.

First decodings are easy, intuitive, and accurate, later ones are easier, and the word becomes a sightword quickly.
Cognitive load is the amount of mental effort your short‑term memory can handle at once. It is small, 4 maybe 5 new bits of information, and fades quickly. When a reading task asks you to try rules, remember exceptions, and hold several sound attempts at the same time, memory overloads and learning stalls.
Traditional sounding‑out makes you hold many separate sounds at once (s + t + r + e + ng + th + s). That quickly overloads memory and leads to errors.
Progressive sounding‑out always manages just two things: the blend so far and the next sound to add. For example, syllable “strengths” is blended as follows:
Progressive sounding-out: there are just two pieces in working memory so even long syllables can be sounded out:
1. the blended sound so far, and
2. the next sound to add.
Worked example — the syllable “strengths”:
At each step, the blending task is small and clear, so working memory never overloads. Each syllable blend is easy, intuitive, and accurate, so the sounds of the syllables are quickly recognised. The sound and shape of the syllable can be quickly remembered. Once all the syllables in the word are decoded, the sound of the word can be quickly sounded out syllable by syllable, and with a few exposures, it becomes a sightword.
