Definition of the word cotton on

The phrase "cotton on" is an Australian and New Zealand English slang term, which means to understand or to be able to comprehend a situation or concept. The expression originated in the mid-twentieth century, and its popularity can be traced back to the cotton-picking industry in Australia during the 1940s. During this time, migrant workers were employed to pick cotton in rural areas of Australia. These workers initially struggled to comprehend the process and the specific techniques required for picking the cotton bolls. As they gradually got the hang of it, they realized that they had "cotten on" to the process. The term caught on and has been a part of Australian and New Zealand English slang ever since. Its usage is still prevalent in both countries today, primarily in informal settings, such as casual conversations and everyday interactions. The expression has also gained popularity in other English-speaking countries, including the UK and Ireland. The exact origins of the expression may be debated, but its widespread usage is indicative of the fact that the term has become a part of the Australian and New Zealand vernacular. It is a unique reflection of the rich cultural heritage and slang terminology that characterizes these countries' English dialects.
