Definition & Meaning of "heaps"in English

What does "heaps" mean in Australian slang?

In Australian slang, "heaps" means a large amount or number of something, and is commonly used as an informal intensifier or quantifier in everyday speech. It is used in casual Australian English to replace words like "a lot" or "many," and can apply to both countable and uncountable things (e.g., "heaps of people," "heaps of time"). The usage developed from standard English "heap," meaning a pile or large quantity, which was extended in Australian informal speech into a general-purpose intensifier.
