I was proofing a document the other day and performed an action which I believe has a proper name, but I am not sure. Are you aware of a technical English usage term that refers to the separation of a compound word at the end of line of text (by use of a hypen) and its continuation on the next line of text. This may occur at the beginning, middle, or end of a sentence. It is rare currently, I suppose, because of word processing programs; but, Is there a term for the breakup and continuation of a word on two lines?
It has been bugging me and I would like to know if I am thinking about a term that does not even exist.
We talk about "hyphenation" to refer to the setting of hyphens generally. What you're referring to is breaking a word over two lines -- and I don't know of a special word for that. It is a type of hyphenation, and normally simply called "hyphenation".
Modern word-processing programs can be set to break words if necessary. They use a hyphenation algorithm to determine where it is possible to insert a word break.
