Like I said at the beginning of the week, every project is different so this tip will look very different for each project, and each person. Try to use more then just words if you can. This will stretch your creativity and may even require you to seek some outside help in creating elements, but will be worth it in the end. Look for words that have implied attributes or characteristics. These sort of words let you have fun and add little elements to help convey their meaning.
The other words to look for would be general objects. These words will allow you to actually get rid of the word and in it’s place, put a graphical element. When bringing in or creating objects, the goal is seamless integration. I tend to look for images with less intricacies and details. Again, this depends on the style of your project, but most fonts aren’t overly elaborate, so keeping your objects equal in their simplicity overall will help the merge feel smoother.
