Sandhi is a Sanskrit word meaning “a putting together.” We get our word (ice cream) “sundae” from “sandhi.” Technically, the word refers to the effect that the end of one word has on the beginning of the next. This happens all the time in Sanskrit, I’m told, and sometimes in spoken English. (I suppose the choice of whether to use “a” or “an” before a word could be attributed to sandhi.)
Anyway, here’s a good example of using sandhi to make a joke.
