The Ilocano word for "stupid" is nengneng.

nengneng is an adjective used to describe someone or something that is lacking in intelligence.

Meaning: lacking in intelligence (adj)

Did you know?

While nengneng is a common term, many Ilocano speakers might actually use Spanish-derived loanwords like tanga or stupido in urban settings to express the same sentiment.
The word nengneng can sometimes carry a much softer, almost playful tone in very intimate family settings, similar to calling a child 'silly'.
In some northern Philippine contexts, calling someone nengneng might be interpreted as calling them 'vacant' or 'empty-headed' rather than just unintelligent.

Ricardo

Angel

Maaramidko met daytoy.
I can do this too.
