The function f(x) takes a word as input and returns a value between 0 and 1, indicating the association of the word with certain concepts. The function is selective for words related to rhyming, containment, and transportation, as well as words with certain letter patterns or structures. The function may also be selective for other concepts not yet identified.

Now, I'd like to run some additional tests to further refine the description of the function. Can you provide me with a list of words that are known to be associated with the concepts of rhyming, containment, and transportation?
