It is to be observed that 'angling' is the name given to fishing by people who can't fish.

The quote "It is to be observed that 'angling' is the name given to fishing by people who can't fish" by Stephen Leacock humorously critiques the difference between the casual practice of fishing and the skills required to truly fish. Leacock, a Canadian writer and humorist, is suggesting that the term "angling" is often used by those who lack the skill or knowledge to fish properly. In his characteristic witty style, he implies that people who are not particularly good at fishing use this more refined term to make their attempts seem more sophisticated, even though their actual abilities may be lacking.

The humor in this quote comes from Leacock's use of irony to point out how language can sometimes be used to elevate something that may not deserve it. In this case, the term angling, which might sound more technical or serious, is used by those who aren't skilled at the sport, perhaps as a way of compensating for their lack of expertise. The joke implies that the more skilled and experienced fishermen simply call it fishing, as it is, without needing to create a more complicated or fancy name for the activity.

The origin of the quote can be traced to Leacock's broader comedic observations on human behavior and language. Known for his lighthearted, satirical writing, Leacock often poked fun at the ways people use language to make ordinary activities sound more impressive. This particular quote reflects his humor and his ability to comment on the absurdities of everyday life with wit and simplicity.

Ultimately, Leacock's quote highlights the human tendency to create complex terms or euphemisms for activities we feel less competent in, while also acknowledging that true expertise doesn’t need extra decoration. The line about angling and fishing is a playful reminder that simplicity and honesty are often more fitting than trying to add layers of sophistication where they aren’t needed.
