Jalajala

Jalajala (also spelled Jala-jala) is a fourth class municipality in the province of Rizal, Philippines. According to the, it has a population of people.

Etymology
What is now the town's Barangay Punta was the seat of an earlier settlement later known as Halaán. During the summer from April to May, the shores of Laguna de Bay along Punta would be filled with small shellfish locally known as halaán.

As is typical with many modern Philippine toponyms, the town's name supposedly resulted from miscommunication between early Spanish visitors and natives. The Spaniards enquired of some natives along the shoreline, "¿Como se llama este sitio?" ("What is the name of this place?") to which the latter replied, "halaán pò," thinking that the foreigners referred to the shells. The Spaniards accepted the response as the name of the place, and began calling it halaán, later corrupting it into Jalajala.

Another folk etymology is that Jalajala stems from an endemic breed of boar called berk jala, which is abundant in the wilds around the town and is depicted on its seal. As with the other story, a Spaniard asked the Tagalog-speaking natives the place's name, and the locals' interjection of "hala-hala” (possibly a hunting chant) was taken by the Spaniards to be their answer.
