"Naman: used in making [1]constrasts; [2]softens requests; [3]emphasis"
1.)Maganda nga siya pero tamad naman. She's really beautiful but on the other hand she's lazy. The naman is being used for contrast.
2)Softens Requests. Basically, if you give a command and you don't want to sound harsh you add naman.
Pakiusap umalis ka naman.*
Please leave now.
3)Emphasis. Emphasis is emphasis and sometimes can be agreement.
Aba! Mataba siyang diyan.*
Di, chunky lang naman.*
(Linapit niya)*
Oo naman! Pinakamataba naman niya!*
Kailangan ko ng new glasses!*
Wow, that person over there is fat.
No, Just chunky.
(Person Comes Closer)
Yeah (I agree/your right)! He's/She's the fattest!
I need new glasses.
I probrably could've used a naman on the last one for emphasis.
Naman in its simplest form can be understood also as "again", "also", "too or so", "really"
Na naman? = Again?
Naman? = Really
Siya naman ay makikinabang - She will also benefit.
Ang tanga naman. = Too stupid. or So stupid.
