What is the difference between ako and nako ?

Ako is ako, nako could be a few things:1. A an exclamation, Ay nako!
2. Not Tagalog. Some sister languages (Central PH) use nako as the ergative case form for their version of "ako", or as a shorter version of the oblique case form (kanako -> nako in speech). "Gihigugma nako ang akong asawa"
3. Tagalog sandhi! If ako follows a vowel, particularly one spelled with "a", then the resulting sandhi would produce words like "walako sa bahay" "papunta nako". You can tell this shortened "ako" from a true "ko" based on clitic positions.

na’ko *There should he an apostrophe before “ko” where the “a” would be in “ako”.Its “na” + “ako”.You will see it as “nako” more often but Its good to know the basics so that you can understand things better.

Interesting that in some parts of the Philippines nako is used meaning me, I, instead of ako which by the way also occur in the examples of tagalog.com when searsching for nako Indeed, Tagalog sandhi! I

@roelands Nako will need context because it can mean many things like an informal contraction of either (ina ko or na + ako
