Let's figure out what a pattern is. A pattern is a certain template or repeated structure that we notice in different things. For example, when you notice that every morning starts with coffee and news — this is also a kind of pattern in your life. These templates help us predict what will happen next, or how something works.
Regarding the stress in the word “pattern”, the stress should be placed on the first syllable, that is “páttern”.
So, a pattern is a kind of code or signal that we see in our daily affairs. It helps us navigate and make predictions. Imagine if every time you turned on your favorite playlist, the same first song always played — this is also a pattern. It creates a sense of stability and familiarity.
