The core particles

ParticleCore meaningExample
naalready · now · by this timeKumain na ako. — I've eaten already.
pastill · yet · first (before doing)Gutom pa ako. — I'm still hungry.
lang / lamangonly · justSandali lang. — Just a moment.
din / rinalso · tooKumain din siya. — She ate too.
baquestion flagKumakain ba siya? — Is she eating?
namansoftener / on the other hand / in returnSige naman. — Oh, go ahead.

Two different things here: lang/lamang are just the short and long forms of one word (use either). But din/rin and daw/raw are sound-conditioned — the r- form follows a vowel or w/y, the d- form follows a consonant.

na vs pa — the aspect pair

na says 'already / now' and pa says 'still / yet' — they cover the territory English handles with tense and 'already/still/not yet'.

TagalogEnglish
Kumain na ako.I've already eaten.
Kumakain pa ako.I'm still eating.
Hindi pa ako kumakain.I haven't eaten yet.
Wala na akong pera.I no longer have money.
Mayroon pa akong pera.I still have money.
Umalis na siya.She has left.
Nandito pa siya.She is still here.

ba — the question flag

Yes/no questions in Tagalog don't need word-order gymnastics: insert ba after the first word and the statement becomes a question. One wrinkle: the pronoun ka 'you' slides in before ba (Kumakain ka ba?), while other words follow it (Kumakain ba siya?).

TagalogEnglish
Kumakain siya.She is eating.
Kumakain ba siya?Is she eating?
Kumakain ka.You are eating.
Kumakain ka ba?Are you eating?
Pupunta ka bukas.You're going tomorrow.
Pupunta ka ba bukas?Are you going tomorrow?
