The post-it method. Write your words on post-its and stick them up around quirky places that do have a connection to the ideas you’re describing. The added creativity involved in connecting the abstract concept to the object will help you remember it as you spent more time contemplating the word and making it ’sticky'

The Language Play Method In addition to associating the concept with an object, you can also use the linguistic characteristics of the word you’re trying to remember. This can be sound, spelling, etymology. Find what your word rhymes with, associate the sound of the word with its meaning, or research exactly where it comes from.

Chunks of Language Instead of individual words, the idea is to study chunks of language, that could be short sentences or little phrases that you can use. So instead of “hungry” you’d learn “I’m so hungry, I want to eat” or instead of “where” you’d learn the whole phrase “where is the bathroom?”. For your question of abstracts, this can be helpful because you now have a full sentence to write down and something that you can sing to yourself.
