"Wert about" is an old-fashioned phrase that means "were walking around." There are several synonyms that can be used in place of this phrase, depending on the context. Some alternatives include wandering, strolling, meandering, roving, ambling, sauntering, traipsing, and rambling. Each of these words conveys a sense of movement or exploration, without necessarily implying a specific purpose or destination. For example, one might say "we were wandering the streets of Paris" to describe a leisurely sightseeing excursion. Alternately, "we were traipsing through the forest" might describe a more adventurous hike or exploration of nature. Regardless of the particular synonym used, the important thing is to convey a sense of movement and exploration.
