I’ve always liked words which end in “itch” or “inch” even though sometimes I can confuse one with another due to spelling similarities. Each of these words comes with an attached sound. For example, the word “glitch”–one can almost hear the sound of a “click” when a malfunction happens. The word “twitch” too–one can almost feel the twisting of the facial muscle. The word “snitch” is so easy to remember that I remembered it the first time I encountered it in a TV show with a government informer in it.
Many of these words are commonly used–they are formal words with a feel of being a slang.
glitch: an unexpected defect, fault, flaw, or imperfection

skitch: hold on to the back of a moving motor vehicle so as to be pulled along while riding a skateboard.

snitch: an informer; to inform on someone.
