The phrase "continued to" is frequently used to indicate that an action or behavior persisted without interruption. However, there are many other ways to convey the same idea using synonyms, such as "persisted," "kept going," "remained," "endured," "proceeded," "maintained," "sustained," "persevered," "carried on," "stayed the course," and "pressed on." Each of these words has slightly different connotations, so it's important to choose the one that best fits the context and tone of your writing. Experimenting with synonyms is a great way to expand your vocabulary and add variety to your language.
