Words you can use twice in a row.

Another thread made me think of this. Lets collect all the words that can be validly used twice in a row.

It's it's own chaser.

POE is really, really good. I'll still be playing when I'm a great, great grandfather.

That might be cheating, but Ill allow it.

Must be used in a sentence, otherwise its wild speculation

Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo.
Can can can can can can can can can can.
James while John had had had had had had had had had had had a better effect on the teacher.

You can use "had" infinitely in a sentence and still be grammatically correct technically, so I don't think that counts. But the other two are the longest ones that I know of.

Any word can be used more than once if you talk talk with with a a stutter stutter.

Fixed; not actually the same word, which means you can't say that that is fine.

since when is it's not a word? Contractions turn two words into one, therefore, word.

Words that can be different parts of a sentence (say a noun and a verb, or an adjective and a noun) e.g. I can taste taste. I ate the orange orange.

Homonyms e.g. I can't bear bear.

And do titles/proper nouns count, or is that cheating? Then you could have sentences like, "I read the first edition of Of Mice and Men."
