It depends on how you’ll use the term “ko.” KO ko, pron. my, I ang libro ko = ang aking libro my book ang bahay ko = ang aking bahay my house Kinakain ko ito. I eat this.

@mataripis. if 2) is unintentional, it should've been.. Nakain ko ang tinapay... both sentences seem OK to me.

i never studied the patterns of grammars but for me 1.) is intentional and 2.) is unintentional..

I agree with JoYcE... both these sentences are translated to: "I ate the bread this morning" "kain" is the tagalog root verb means "eat". In english, we use 'affix' (such as prefix & suffix) to produce an inflected or derived form. we call it in tagalog 'panlapi' (unlapi - beginning, gitlapi - middle, hulapi - end) as in "UM" & "IN" usually added to a verb. the two tagalog sentences however, differ from the way they're asked: "Kinain ko ang tinapay kaninang umaga" (what did you eat this morning?) .... answer = 'tinapay' (bread) - noun "Kumain ako ng tinapay kaninang umaga" (what did you do this morning?).....answer = 'kumain' (ate) - verb. :)

Both sentences have the same meaning which is "I ate the bread this morning." The use of KO and AKO is dependent on the verb. For "um" type of verb (as in kUMain), "ako" is used as subject, with kINain, "ko" must be used. "Ako" is used when the focus is yourself, while "ko" if the focus is a verb or noun. Ako and ko, although they both refer to the speaker are not interchangable. I hope it helps.
