In Spanish, many words are categorized as either feminine or masculine, with each form having a slightly different spelling. For instance, “lindo” is the masculine form of the word and ends in “o”—you’d use this form of the word to flirt with a guy. If you were flirting with a woman, you’d use “linda” (LEEN-dah), which is the feminine form of the word (ending in “a”). “¡Tu eres super linda!” (Tu air-es SOO-per LEEN-dah) means “You’re super cute!”

“Guapo” is the masculine form of the adjective, which is why it ends in “o. ” To flirt with a woman, you’d use “guapa,” which is the feminine form of the adjective. “¡Te ves guapo!” (Teh vase GWAH-poh) means “You’re looking handsome!”

Like other Spanish adjectives, “bonito” changes to “bonita” (boh-NEE-tah) when you’re flirting with a girl. Stick with “bonito” if you’re chatting with a guy, though! “¡Qué bonito eres!” (Kay boh-NEE-toe air-es) means “How cute you are!”

“Tierno” is the masculine form of the word. It switches to “tierna” (tee-ERR-nah) when you’re speaking with a woman. “¡Creo que eres tierno!” (CREH-oh kay air-es tee-ERR no) means “I think you’re sweet. ”

“Precioso” changes to “preciosa” (preh-see-OH-sa) when you’re talking to a woman (or are referencing a feminine noun). “Tu eres precioso. ” (Too air-es preh-see-OH-so): “You are charming. ” “Mi sobrina es una bebé preciosa” (Mi so-BREE-na es oon-uh beh-beh preh-see-OH-sa) means “My niece is a beautiful baby. ”

“Monada” is the only form of this word—you don’t change it to “monado” for masculine nouns. “¡Hola, monada!” (OH-lah moh-NAH-da): “Hello, beautiful!” “¡Qué monada de gatita!” (Kay moh-NAH-da day gah-TEE-tah) means “What a cute little cat!”

As an adjective, “bello” falls into the masculine and feminine adjective rule. Stick with “bello” when you’re flirting with a cute guy, and opt for “bella” (BEH-yah) when speaking with a cute girl. “Eres tan bella que me has hecho olvidar mi piropo” (Air-es tan BEH-yah kay meh yas ay-cho ol-vee-dar me pee-ROH-po) means “You’re so beautiful that you made me forget my pick-up line. ”

To keep your flirty comment grammatically correct, use “hermosa” (err-MOH-sa) when you’re complimenting a girl and “hermoso” when you’re chatting with a guy. “Tu eres hermoso” (Too air-es err-MOH-so) means “You are so beautiful. ”

As an adjective, “bueno” is used to modify male nouns. With feminine nouns, “buena” (BWE-nah) is used instead. “Ella está buena” (Ey-ya es-tah BWE-nah) means “She is looking good. ” To really dial up your flirting, use a superlative like “buenísima” (BWE-nee-see-mah), which means “very good-looking”). For instance, you could say “Tu eres buenísima” (Too air-es BWE-nee-see-mah), which means “You are very good-looking. ”

“Eres increíblemente adorable” (Air-es een-CREHB-la-men-tay ah-door-AH-blay) means “You are incredibly adorable. ” “Tu perrito es tan adorable” (Too per-REE-toh es tan ah-door-AH-blay) means “Your puppy is so cute. ”

If you’re flirting with a guy, use “atractivo,” which is the male form of the word. If you’re chatting it up with a woman, use “atractiva” (uh-track-TEE-vah), the female form of the word, instead. “Lucas, eres un hombre muy atractivo” (LOO-cuss, air-es oon OHM-bray MOY uh-track-TEE-voh) means “Lucas, you are a very attractive man. ”
