01
Separate essential from interesting
When a term is unfamiliar, ask whether you need it to follow the current argument or example. Look up blocking terms first. Keep a short list of interesting terms for later rather than opening a new detour every few sentences.
02
Make a definition you can use
Write the term, a plain-language meaning, and a tiny example. If possible, add a non-example: something that looks similar but does not fit. This checks the boundary of your definition.
03
Return to the original passage
Read the passage again after the lookup. A definition only helps if it clarifies the problem that sent you looking. Revise your wording if the context reveals a different meaning.
04
Keep the list small
Select a few terms worth keeping at the end of a session. The goal is a vocabulary that supports your next step, not an impressive collection of copied definitions.
