Formal:
* Mga gisantes na itim ang mata: This is a literal translation and is the most accurate.
* Mga patani na itim ang mata: This is another literal translation, using the word "patani" which is a more general term for beans.
Informal:
* Itim na mata na gisantes: This is a more casual way to say it.
* Gisantes na may itim na mata: This is also an informal way to say it, emphasizing the black eyes.
You can also use the English term:
* Black-eyed peas: This is perfectly acceptable in Filipino, as English words are often used in everyday conversation.
The best choice depends on the situation and who you're talking to. For example, you would likely use the more formal translations in a recipe or article, while using the informal translations or the English term in a casual conversation.
