ascent
[C/U] Both
This term carries a strong sense of effort and intentionality. It is frequently used in technical, geographical, or aviation contexts to describe a physical climb, where the focus is on the process of gaining altitude rather than the peak itself. In a social or professional context, it describes a steady rise in status or power. It suggests a trajectory of success that is often gradual and hard-won, such as a political ascent, contrasting with a sudden jump in rank.
Countable when referring to a specific climbing trip or a particular slope. Uncountable when referring to the general process of rising in rank or altitude.
