Build a Bridge
Not all words have a history good enough for our purposes. Let's not forget that English is still inherently a Germanic tongue which means not all words are going to have a Latin heritage. Besides, even words with Latin origins might not qualify for an etymology hack at times, especially if it has corrupted beyond recognition. Those are situations ripe for mnemonics. You can call this trick anything from visualization to word-association and from mnemonics to bridge-technique. All it involves is creating a mental bridge between the foreign word and its meaning in order to spoof a connection. This is just to fool your brain into seeing an organic connection between the two.
Take, for example, the word ojo. That's Spanish for eye. Now, ojo doesn't look anything like eye and the two words don't even have a common family tree. So, instead of etymology, we bank on our creativity. We make ojo look like eye to our brain with a little imagination. Look at the Spanish word again. Dwell on it for a while. Doesn't it look like an owl with two eyes and a beak? Picture the two o's as the two large eyes of that owl and the j as its beak! Now every time you think eye, you'll picture this owl and that will lead you to ojo.
Of course, this was a very easy example; but the idea can be applied to any word regardless of how complex it appears. I have used it even with words like cempasúchil!
Here's another example to illustrate the trick: Mujer, Spanish for woman. Mujer looks and sounds a little like music. It also kind of rhymes with teacher. Let's combine the two. Imagine having a woman as your music teacher at school. Make your imagination as vivid as possible. Give her a character, a personality. Maybe she's super sweet and kind? She is very old? She sings like a bird? She can play like 6 different instruments?
The more details you put in, the easier she will be to recall. Now every time you think woman, you'll recall this music teacher who will lead you to mujer. Mujer also rhymes with hair, so you can give your imaginary music teacher a distinct hairdo to reinforce the connection.
