Which strategy would be effective for a student to understand the word "impassable"?

Using structural analysis is effective for understanding the word "impassable" because this strategy involves breaking down the word into its meaningful parts: the prefix "im-", the root "pass", and the suffix "-able".

The prefix "im-" typically means "not", while "pass" pertains to the action of moving through or across something, and the suffix "-able" indicates the capability of something. When the parts are combined, "impassable" conveys the meaning of something that cannot be passed through or crossed. This method allows students to analyze the components of the word and derive meaning from them, fostering a deeper understanding of vocabulary through morphology.

Context clues might provide some hints about the meaning when "impassable" is used in a sentence, but without breaking down the word itself, the student may miss the full depth of its meaning. Phonetic decoding focuses on the sounds and pronunciation of the word, which does not necessarily help with understanding its definition. Word association involves linking the word to similar words or concepts, but it may not provide clarity on the specific meaning of "impassable". Overall, structural analysis directs students to the intrinsic components of the word, leading to a clearer understanding of its meaning.
