"In the context of" is the phrase that changes how well you look words up.
I have used this for years. I did not invent it; it is something CELTA taught me. Adding it gets you the meaning of a word inside the topic you are actually reading about. You are not just recording a word, you are understanding it, and your brain holds onto it far longer as a result.
A concrete example
Look up material on its own and you will get the everyday sense: a physical substance, fabric, stuff things are made of.
Now look up "material in the context of accounting" and you get something entirely different: significant enough to matter, the materiality concept. Two unrelated meanings. Look it up the ordinary way while reading an accounting text and you will misread the whole sentence.
How to use it
Use a translation tool or ask an AI assistant. The thing to remember is to always name the domain: "in the context of" plus the field you are reading in. The explanation you get back is far more precise and far more detailed.
The reason this works is that you are not learning an isolated word. You are learning a word attached to the place it lives, and that is what sticks.
