Key Concepts & Vocabulary
TermDefinitionExample
EtymologyThe study of the origin of a word and the historical development of its meaning.The etymology of 'disaster' comes from the Italian 'disastro', which means 'ill-starred event', from Greek 'dis-' (bad) and 'aster' (star).
Root WordThe foundational part of a word that carries its primary meaning. It cannot be broken down further.The root 'port' (from Latin 'portare', to carry) is the foundation for words like 'transport', 'import', and 'portable'.
PrefixA word part added to the beginning of a root word that modifies its meaning.The prefix 'trans-' (across) added to the root 'port' creates 'transport', meaning to carry across.
SuffixA...

Key Rules & Conventions
The Deconstruction Method
Break the word into Prefix + Root + Suffix.
When encountering an unfamiliar word, first try to separate it into its component parts. Isolate the core of the word (the root) and then identify any parts added to the beginning (prefix) or end (suffix).
The Synthesis Principle
Combine the literal meanings of the parts to form a core definition.
After deconstructing the word, define each part. Then, logically combine these smaller meanings to build a hypothesis about the word's overall meaning. For example, 'sub' (under) + 'terra' (earth) + '-an' (related to) = 'subterranean' (related to being under the earth).
Context is King
