This morning I found out the Korean word for 'spine'. Five minutes later, I'd already forgotten it. It certainly won't be in my memory the next time I need to talk about spines!
I think part of the problem is that as an English speaker, there's no direct way I can associate "spine" with "척추". In contrast, if I found out the French - "colonne vertébrale" - that has an obvious link to English words, and I may even remember that for life now. Even the Dutch "wervelkolom" is easier to associate.
Additionally, "spine" is not a word I'm going to use regularly enough to reinforce it -in contrast with, say, words to do with food...
As a native speaker of a language with very different word roots (and an older learner at that!), what are some good tips to learn Korean vocabulary - especially lesser-used words - in a way that I have a chance of recalling it some time later?
I realise that to an extent this is a general language-learning question, but some tips may be specific or particularly relevant to Korean, so I'd like to ask here. I really feel that this is one of the main issues blocking my progress.
