Grammar and Vocabulary Notes

• Primer, segundo, tercer, etc.: These are the words for first, second, third, etc. Primer is a shortened form of primero, and tercer is a shortened form of tercero. They are shortened in this manner when appearing before a singular masculine noun. The forms used here for 11th and 12th are not common in spoken in Spanish.
• Día: Día, meaning "day," is an exception to the rule that nouns ending in -a are masculine.
• Navidad: This word can refer not only to Christmas Day but also to the season in general.
• Amor: This is the word for "love." It can refer not only to the emotion but also to a person such as a sweetheart. It is related to the verb amar. The noun remains masculine even when it refers to a girl or woman.
• Mandó: Mandó is a past-tense form of mandar, which most often means "to mandate" or "to order," but in this case means "to send."
• Perdiz: a partridge or ptarmigan
• Picando: This is present participle of picar, which can mean "to bite" or "to peck at." A literal translation of this line would be "a partridge pecking at pears of the pear tree." Note that here, the present participle functions as an adjective. In standard Spanish, the present participle acts as an adverb, but adjectival use such as this is sometimes seen in poetry, journalistic writing, and translations from English.
• Pera, peral: a pear or pear tree. The suffix -al often refers to a tree or grove of trees. For example, an orange is a naranja, while an orange grove is a naranjal.
• Tortolita: a name for numerous types of doves and related birds. Tortolita is a diminutive form of tórtola, which can also refer to a turtledove. Diminutives such as this, while common in children's music and literature, are not used extensively in serious contexts.
• Gallinita: a diminutive form of gallina, meaning "hen."  A rooster is a gallo.
• Pajarito: a diminutive form of pájaro, meaning "bird." This could be translated as "birdie."
• Anillo: a ring
• Dorado: golden. The word comes from ​dorar, a verb that means to coat something with gold or to turn something brown. The word for gold is oro.
• Mamá gansas: This song is about the only place you'll find this phrase in Spanish. It means "mother geese," but you normally wouldn't say it this way (one way would be gansas madre). Mamá Gansa and Mamá Ganso, however, are common ways of translating "Mother Goose."
• Cisnito: a diminutive form of cisne, swan.
• Lecherita: a diminutive form of lechera, which refers to a female who works with milk. It usually means someone who sells milk, but could be one who milks cows in this context.
• Bailarina: a female dancer, frequently referring to a ballet dancer. It is derived from bailar, the verb meaning "to dance."
• Señor: Although this word is often used now as a courtesy title translated as "Mr.," it can also refer to a lord. 
• Saltando: the present participle of saltar, "to jump"
• Gaiterito: a diminutive form of gaitero, a piper. The related word gaita can refer to instruments such as flutes and bagpipes.
• Tamborilero: a drummer. The related words tambor and tambora can also be used to refer to drums and drummers.
