This is the 176th most frequent Spanish word.
mañana
"Tomorrow" or "morning," depending on context.
In this sentence, 'mañana' is used to refer to the future—the day after today.
Mañana voy al mercado.
Tomorrow I am going to the market.
Here, 'mañana' means the earlier part of the day—the morning.
Siempre me levanto temprano por la mañana.
I always wake up early in the morning.
This usage combines both meanings of 'mañana': the future (tomorrow) and the morning, specifying the time on the next day.
