The Vietnamese phrase "thực ra" means "in fact" or "actually" in English. It is used to introduce a clarification, correction, or to provide more information about a statement.
"Thực ra" can also be used in a more nuanced way to introduce an opinion or a fact that may not be widely accepted. It helps to soften the impact of the statement.
While "thực ra" primarily means "in fact" or "actually", it can also imply a sense of revelation or truth that may not be immediately obvious.
