Is a hyphenated word considered grammatically to be one word or two?

Answer 1

if you're talking about a compound word ("first-order", for example) then syntactically it is one word.

If it's a hyphen to split a word (example, at the end of a line), it's still one word.

Answer 2

Unfortunately many people today take a lot of liberty with words in the manner they type them. However, I don't know of any place in grammar that a hyphenated word would be counted as anything other than one word. A really easy way to remember this is that in most database searching programs, the hyphen is dropped. Here's an example...

If you typed the word "so-so" (meaning something is just ok) into most search programs like this: so-so

The program when searching it would make it look like this: soso
