Remembering words is just like learning Chinese. You know how it came from and why you wrote it like this, so it's easy to remember. Otherwise, rote memorization can only repeat the tragedy of memorizing and forgetting. For example, the word "hand" in Chinese means hand-related, thus forming "lifting", "beating" and "supporting". The word "hand" is equivalent to a simple root and has evolved into many complicated Chinese characters. The same is true of English, except that English is not hieroglyphics like Chinese, paying attention to pronunciation and its evolution is more complicated. But if we find out the root rules of English words, there will be rules to follow in memorizing words, such as the root-"-dict" means "speak" (we can remember words through a simple dictionary, because dictionaries are used to "speak" words). By combining the root "-dict" with other roots or primary words, more advanced words have evolved. For example, the root "pre" means-"before, ahead of time", "before, ahead of time"+"dictum" = = predict. Another example is that many other advanced words can be formed by combining the root pre with other roots or basic words:

Preschool class (preschool+school → preschool)

Prehistoric history

Prefix Prefix (Prefix+Fixed → Fixed in front → Prefix)

Preposition Preposition, Preposition (Preposition+Position → Position First → Preposition)

Prepayment in advance (prepayment+payment)

Prefabrication by pre-construction (pre+construction)

Preface, Preface (Pre+Slow Operation → Advance Operation → Preface)

Preventive measures (advance+attention → prevention → prevention)

(in time) before (pre+cede goes → first → [in time] before)

Precedent precedent (pre+ced goes +ent→ progressive things → precedent)

Teach by example; Motto (pre+accept take → famous words taken before → motto)

Area and scope of jurisdiction (pre +cinct binding → pre-binding → scope)

Abrupt cliff (front +cipice head → front end → cliff)

Precipitation falls in haste (early stage +cipit head → action → early landing → landing, descending)

Precision, precision (pre-cutting +cisse cutting → pre-cutting → precision)

Remove obstacles; Blocking (early+including closing → early closing → blocking)

Early maturity (pre-ripening+ripening → pre-ripening → early maturity)

Susceptibility to illness, addiction (pre+temperament → temperament retention → addiction)

Pre-occupation concentration (pre-occupation+occupation → priority occupation (attention) → concentration)

Prescient has foresight (pre+scientific knows → know in advance)

Privileged right, privilege (pre +rog requirement+passive → pre-requirement → (ownership) privilege)
