signalize

To signalize means to mark something in a clear and noticeable way, especially so that it stands out as important, remarkable, or worthy of attention. A city might signalize an anniversary with public ceremonies, or a writer might say that a bold decision signalized a turning point in history. In this sense, the word suggests more than simple mention; it suggests making the importance of something plain.

The word can also mean to indicate, announce, or make known by a sign or signal. In older or formal writing, a gesture, flag, light, or sound may signalize danger, arrival, approval, or some other message. This use stays close to the idea of communication through signs.

There is also a modern technical use, especially in traffic and transport. An intersection or crossing can be signalized, meaning that it has been equipped with traffic lights or other control signals. Here the word is not about honor or ceremony at all; it is about installing a signaling system.

Overall, signalize has a formal feel and is less common in everyday speech than words like mark, highlight, indicate, or equip with signals. Still, it is useful when you want a single word that can cover these related ideas: making something stand out, showing something by a signal, or putting signals in place.
