While dictionaries are helpful tools, understanding Latin and Greek roots gives students a powerful strategy for decoding hundreds of unfamiliar words independently. Since approximately 60% of English words contain Latin or Greek roots, a student who knows 'auto' (self), 'bio' (life), and 'graph' (write) can figure out 'autobiography' without looking it up. This skill is especially valuable during standardized tests and when reading complex academic texts where immediate dictionary access isn't available. It also helps students retain vocabulary longer because they understand the logic behind word construction rather than memorizing isolated definitions.
This is completely normal at the advanced level. Start by teaching your student that they should underline or highlight each morpheme in different colors as they analyze a word. For example, in 'uncontrollable,' they'd mark 'un' (prefix), 'control' (root), 'able' (suffix), and 'e' (sometimes words drop letters). Practice with 'sandwich words' where the root is in the middle, then move to words with both prefix and suffix. Begin with words where morphemes are clearly separated (like 'unhappiness') before tackling words where letters blend together (like 'misspell' with double s).
Your student should be ready if they can consistently identify common prefixes (un-, re-, pre-, dis-) and suffixes (-tion, -ment, -ness, -able) in grade-level texts and explain how each morpheme affects meaning. They should also understand basic concepts like 'a prefix comes before the root' and 'a suffix comes after.' If they can do these things, they're ready for advanced roots and more complex word structures. However, if they're still confused about how prefixes and suffixes change meaning, it's worth reviewing those simpler concepts first before tackling advanced Latin and Greek roots.

English has many exceptions because it borrowed words from multiple languages. If your student encounters an outlier word (for example, 'irregardless,' which technically breaks standard rules), use it as a teaching moment. Acknowledge that English isn't perfectly logical, then explain the exception: 'Most roots follow patterns, but some words are exceptions that we need to remember.' This normalizes that advanced language learning sometimes requires noting irregular cases and helps your student develop a growth mindset about vocabulary challenges.
Ask your student to create sentences using the analyzed words in ways that demonstrate full understanding of both denotation and connotation. For instance, a student might write two sentences with 'misconstrue'—one in a neutral context and one in an emotional context—showing they grasp subtle meaning differences. You could also have them find related word families (all words sharing the same root) and create a visual diagram. Another extension: research the original Latin or Greek root word and its meaning in the original language, then trace how English borrowed and modified it—this adds a historical-cultural dimension to vocabulary learning.
