It depends on what you’re memorizing. If you can hold those words in your natural memory you might not need an image for each word.
For “and” I use an image of a large iron ampersand symbol (&). It’s large and heavy, so can interact with other images. I only insert it in the scene if I forget the word “and” on a recall.
I don’t have an image for “also”, but probably would use an image of someone named Ilsa.
“Because” contains the words “bee” and “cuz”. Other similar words: “beaker”, “beak”, “BICA”.
I’d probably use a bee, because I also use a bee for the word “betray”, which is a bee carrying a tray. He is getting stabbed in the back by antique perfume sprayer (the kind found in old cartoons), which reminds me of the Esperanto word perfidi (to betray).
