Haddest the upper hand, a phrase used to describe a situation where someone is in a dominant position, can be replaced by several synonyms, each with slightly different connotations. One option is to say that someone is in a position of power or authority, which suggests that they have more control or influence than others in a given situation. Alternatively, the phrase "held sway" can be used to indicate that someone has a strong influence over others, whether through their status, abilities, or charisma. Other options include phrases like "held the advantage," "took the lead," or "held the trump card," which all suggest a position of strength or superiority in a given situation.
