Etymology

What is now the barangay of Punta was the seat of the early settlement later known as "Halaan".
During the summer months of April and May, the shores of Punta along Laguna de Bay were
covered with a variety of shells locally known as halaán.

As is typical with many place names in the country, it resulted from the linguistic barrier between
early Spanish visitors and natives. The Spaniards would ask "¿Como se llama este sitio?"
("What is the name of this place?"), to which the natives replied "halaán pò," thinking that the
foreginers were asking the name of the shells. The Spaniards accepted the response as the
name of the place, and began calling it halaán, which was later morphed into Jalajala.
