Another one suggests that it came from a Spanish word "Ca – Naic" meaning "neighboring place" by which its mother town was the present Maragondon.

Naic was the western slope of the volcano until its internal eruption which led to the sinking of its apex in its present condition.

When the Jesuits discovered Maragondon in 1627, its total land area covers the whole of Naic, Ternate, and Magallanes (Vance; Saulo and De Ocampo, 1990; Medina, 1992).

In 1758, the Jesuits founded a community in the western bank of the river (present Barangay Muzon) and made it into a "sitio" with a visita still under Maragondon.

These were as follows: The prominent people who paved the way for the revolution in Naic included former gobernadorcillos and capitanes municipal; namely, Cirilo Arenas, Gregorio (Goyo) Jocson, in whose house General Aguinaldo recuperated from illness, Benito Poblete, and Tobal Bustamante.

[6][better source needed] A sprinkling of upperclassmen could also be found in other towns of Cavite whose wealth came from rural landholdings, urban properties, and/or successful business ventures.

The Cuencas of Bacoor, the Papa, De Castro, Valentin, and Arenas families of Naic, the Darwins of Indang, who were/are Spanish nobilities and margraves with ranks of Duques, Marquis, Condes and Vizcondes, pertained to this class.

Situated beyond the southern portion of Naic is Indang and the western boundary is shared with Ternate and Maragondon.

Majority of the upland towns and some of those in lowlands trade with Naic due to its strategic geographical position.

Investors established their businesses in different industrial estates that magnetized people to migrate to Cavite due to job opportunities the province offers.

The Catholic population of Naic is primarily served by the Diocesan Shrine of the Immaculate Conception Church.
