In modern society, symbols play an irreplaceable role. In cities, we can often see road signs, shop signs or public billboards. In addition, we often need to sign various agreements or documents on various occasions in order to conduct various legal transactions or activities.
Besides common usage, symbols have many other extended meanings. For example, I often see the phrase "sign up", which means to sign up for an organization or participate in an activity. In the network era, many applications or websites require users to register first and accept their terms of service. At this time, we can use the phrase "registration" to mean "registration".
In addition, symbols are usually used to represent events, phenomena or omens. For example, "the first snow of the year is a sign that the cold winter is coming". In this example, "sign" means "omen". Another example is "a smile is a sign of happiness". In this example, "sign" means "sign".
In a word, sign is a very common word, which can be both a noun and a verb. Besides indicating cards or symbols, it can also be extended to indicate omen, display or symbol. It plays an important role in our life, making it easier for us to express ourselves in daily communication.
