The words 'trash', 'rubbish', and 'garbage' are often used interchangeably in English, although they have slightly different connotations. Trash is a general term that refers to unwanted or discarded objects, while rubbish is more commonly used in British English to refer to household or commercial waste. Garbage, on the other hand, is an American English term that is often used to refer to more general waste or refuse. Despite their differences, all three words can be used to describe unwanted or discarded items. It is worth noting that while these words can be countable or uncountable in the Oxford English Dictionary and the Collins English Dictionary, they are often treated as uncountable in language learning materials. However, Trash can be used in both countable and uncountable forms, as it can be used to refer to a single piece of unwanted material, or as a general term for waste. Similarly, Rubbish and garbage can also be used in countable forms, as demonstrated by their respective plural forms, 'rubbishes' and 'garbages'. Furthermore, the Oxford English Dictionary and the Collins English Dictionary do not provide standard countable forms for these words, and they are generally used in their uncountable forms in formal writing. Finally, it is interesting to note that the plural forms 'trashes', 'rubbishes', and 'garbages' are often used in informal contexts, such as in conversation or in online articles, but they are not typically used in formal writing.
