The word "sat up" is a phrasal verb, comprised of the verb "sit" and the particle "up".
The verb "sit" originates from the Old English word "sittan", which has Germanic roots. It has remained relatively unchanged throughout the centuries.
The particle "up" has a complex etymology. It is a descendant of the Old English word "uppe", which in turn comes from the Old Norse "upp". Both "uppe" and "upp" indicate elevation or movement toward a higher position. These words can be traced back to the Proto-Germanic word "up", meaning "up" or "above".
When combined, "sit" and "up" form the phrasal verb "sat up", which means to rise from a reclining or lying position into an upright sitting position.
