4 To execute a threat or attack — COMMON Common
Unfortunately, carry out is often used in news reports about negative actions being executed. Criminals carry out robberies. Terrorists carry out attacks. Someone might carry out a threat they previously made. The phrase emphasizes that the action moved from intention to reality — the threat wasn’t empty; it was actually done.
💎 Vivid Example

5 Food to take away (Noun — American English) — COMMON Common
In American English, carry-out (often hyphenated or written as one word) refers to food you order at a restaurant but take home to eat rather than dining in. It’s similar to “takeout” or “takeaway.” You might call a Chinese restaurant for carry-out. A pizza place might advertise “Carry-out special: $9.99.” This usage is mainly American — British speakers typically say “takeaway.”
💎 Vivid Example

6 To physically transport something outside — LESS COMMON Common
In its most literal sense, carry out simply means to pick something up and take it outside or out of a place. You might carry out boxes from a building. Movers carry out furniture. This meaning is straightforward and physical, though less frequently used than the figurative meanings above.
💎 Vivid Example
