No words with similar sound with Keyword method

HI,

I’m learning German, and as many others, I try to use the keyword method to remember the words. If you don’t know, the idea is simple: find a word, or several words the reminds you to the original word, and make an image that conveys the meaning of the German word. And here is my problem. In quite a few cases, I just can’t find any words that sounds similar of the German word. Even if I try to split the word to syllables, I can’t find any association. I wouldn’t like to show example, because I would like to solve this problem in general, not per word.

So, what do you do, when so similar word come to you mind?

If you post a few examples, we could help brainstorm mnemonics.
