Means 'the shore' or 'the edge'. Refers specifically to the line where water meets land. 'Estamos en la orilla' (We are at the shore).
Let's go to the beach.

'Playa' is the universal and most common word for beach throughout Latin America and Spain. There is very little regional variation for this specific noun.
While 'playa' is standard, you will also hear the word 'cala' frequently, which refers to a small bay or cove, often rocky.
'Playa' is the standard term. However, people often refer to a beach vacation as 'ir a la Costa', referring to 'La Costa Atlántica' (the Atlantic Coast), where the country's main beach towns are.
In some parts of the Caribbean, you might hear 'balneario', which refers to a seaside resort or a developed beach area with amenities.
Saying 'el playa' instead of 'la playa'. — In Spanish, nouns have a gender. 'Playa' is a feminine noun, so it must always be used with the feminine article 'la' (the) or 'una' (a).
Confusing 'playa' (beach) with 'plaza' (town square). — These words sound similar but have very different meanings. 'Vamos a la playa' means you're going to the beach. 'Vamos a la plaza' means you're going to the central square in a town or city.
Pronouncing the 'll' in 'playa' like an 'L'. — The 'll' in Latin American Spanish is pronounced like the 'y' in the English word 'yes'. So, 'playa' is pronounced 'PLAH-yah', not 'pla-la'.
