signalise

Signalise is a verb used in English, primarily in British English, meaning to signal or to communicate by signals, or to draw attention to something through signaling. It is transitive and takes a direct object, as in “to signalise a crossing” or “to signalise a reminder.”

Etymology and spellings: The form is built from the noun signal plus the -ise suffix; it corresponds to the American English “signalize.” The past participle is signalised in British usage and signalized in American usage. Related noun forms include signalisation (British) or signalization (American), referring to the act or process of signaling.

Usage: In transportation engineering, a road junction can be described as signalised when it is equipped with traffic signals. In other contexts, to signalise can mean to mark or highlight something by signals or markers, such as signaling events in a timeline or alerting observers to a state change.

Alternatives and related terms: Common synonyms include indicate, signal, or cue. American writers may prefer “signalize,” while “signalisation” or “signalization” denotes the process in American usage. The word is most commonly found in more formal or technical prose and may be used in fields dealing with signals, indicators, or traffic systems.
