Reshuffle letters into familiar chunks rather than scanning linearly.
Practise spotting common letter chunks, prefixes, suffixes, and frequent pairings, and physically or mentally regroup the letters rather than reading them in the given order. Note which letters are rare and likely anchor the word. As you improve, set tighter time limits so retrieval becomes more automatic and less effortful.
The usual trap is fixating on the presented order, which blocks the rearrangement; deliberately break the sequence by moving vowels and consonants apart. Forcing a brute-force search of permutations is slow and rarely needed. If a word will not come, switching tactics, trying a different anchor letter, often triggers the insight faster than grinding.
