Here's a breakdown:
* Direct meaning: You're using the words in their standard, dictionary definitions. There's no hidden meaning or symbolism.
* No exaggeration: You're not embellishing or making things seem bigger than they are.
* No figurative language: You're not using metaphors, similes, idioms, or other figures of speech that imply something other than the literal meaning.
Examples:
* Figurative: "I'm so hungry I could eat a horse." (This is an exaggeration, not to be taken literally.)
* Literal: "I ate a sandwich for lunch." (This is a straightforward statement about a real event.)
Why does it matter?
* Clarity: Using "literally" helps ensure your meaning is understood accurately.
* Honesty: It avoids misleading or exaggerating, which can be important in communication.
* Humor: Sometimes, using "literally" ironically can create humor, highlighting the absurdity of a situation.
Important note: "Literally" is often misused in casual speech, where people might say "literally" when they mean "figuratively" or "really." This is considered incorrect and can lead to confusion.
