Aguinaldo is a word with a number of Christmas associations: in Cuba it is a vine with blue flowers that blooms in the winter; in the Philippines and Puerto Rico it is an early morning mass in Advent; in much of Spanish America it is a name for Christmas presents; in Honduras, Costa Rica and Ecuador the term refers to the annual Christmas bonus given by employers; and in Spain and the Spanish Caribbean it is a song sung by visiting carolers.
Here is an example of a Spanish aguinaldo:
Todo los años venimos,
A cantar por este tiempo
Las coplas del aguinaldo
De Divine Nacimiento.
A esta casa liegamos
Casa rice y principal.
Cantaremos y principal,
Tomaremos si nos dan.
De la sacrista sale
El cura bien revestido
A darle felices pascuas
Al Nino recien nacido.
Every year we come
To sing at this time
The verses of the aguinaldo
Of the divine birth.
We come to this house,
A rich and illustrious house,
We will sing and we will drink,
If you give us something.
From the sacristy comes
The priest, finely attired,
To give Christmas greetings
To the new-born babe.
