Some word a more difficult to mnemonicize. For instance, conventional. Now, I would think to myself: "convent," a place where nuns live, but then how would I relate that to the word conventional? What is conventional about a convent? Perhaps, when dealing with words like this, it would be wise to compare. In this case, I could draw a conventional convent between two more unconventional convents--though what would they look like? The convent in the middle could feature certain abstracted features. The flanking convents could be painted different colors. Honestly, this is a little insight into how I think about these things. My goal to to make the words and images as quick, easy, and encodable as possible, without having to spend a week on the drawings, lol.
