Is there a name for using a word twice in a row to express different levels of a similar thing? [duplicate]

There are a few phrases myself and others around me will use to change the meaning. The first example is “out”:

Shall we go out? — meaning “Shall we go to the pub?”

vs

Shall we go out out? — meaning “Shall we go to a club?”

And my second example is “home”:

“I’m going home later” — meaning “I’m going back to where I live when at university”

vs

“I’m going home home later” — meaning “I’m going back to where I live when not at uni, (probably my parents’).”

I’m curious if this usage of repeating a word to express different levels of the same thing has a name?

This question is different from What is the term for the double consecutive use of a word with stress on one of the words to alter its severity? - here, there is no emphasis on the second word - in fact normally I think the emphasis is on the first word!

Solution 1:

This is known as contrastive focus reduplication.

In linguistic terms, this kind of repetition is called reduplication. Reduplication is when a word, an element of a word, or a phrase is repeated. This can often result in change of meaning or tone. It happens in many languages, not just English, and there are many types of reduplication. There’s rhyming reduplication (razzle-dazzle, hoity-toity), exact reduplication (bye-bye, din-din), ablaut reduplication (ding-dong, zig-zag), and shm-reduplication (baby-shmaby, fancy-schmancy).

LIKE–like, as seen above, is an example of contrastive focus reduplication (sometimes also called lexical cloning or the double construction).
