馬場 (baba) combines 馬 (ba, "horse") and 場 (ba, "place"), giving the compound the literal sense of a place for horses.

In horse-racing coverage, 馬場 (baba) often refers to the track surface itself, so descriptions such as dry, muddy, or firm 馬場 concern running conditions rather than the entire venue.
