Ta
The Uruguayan all-purpose "okay" — "está" filed down to one syllable, opening, closing and punctuating half the conversations in Montevideo.

Hear it in context
—¿Nos vemos a las ocho en la rambla? —Ta, dale.
'Shall we meet at eight on the seafront?' 'Okay, sure.'
Ta, ya entendí, no me lo repitas más.
All right, I've got it, stop telling me.
Pasame el termo, ¿ta?
Pass me the thermos, all right?
What It Actually Means
Ta is está with everything else sanded off, and it does the work of half a dozen English words: okay, fine, right, agreed, got it, that’ll do, enough. It can be a whole reply (—¿Te paso a buscar? —Ta), an opener (Ta, escuchame una cosa), a closer (Ta, nos vemos), or a tag question hung on the end of an order (no te olvides, ¿ta?). Nothing else marks a speaker as Uruguayan so quickly and so cheaply.
Where It Comes From
From está — third person of estar, as in está bien. Uruguayan Spanish aspirates and drops syllable-final consonants hard, and the two-word está bien collapsed first to ta bien and then, in the agreement sense, to ta on its own. It is often written tá to keep the accent that marked the vanished syllable; both spellings are ordinary, and neither is more correct.
How Natives Use It
Constantly, and stacked. Ta, dale is agreement twice over. Ta ta ta, said quickly, means “yes yes, I know, move on”. Ta, bo is agreement plus a shrug. Tone carries all of it: a flat ta accepts, a rising ¿ta? checks, and a long one with a sigh in it concedes something you did not want to concede. It is not rude in any register, but it is unmistakably informal — a Uruguayan writing to a ministry types de acuerdo.
Common Pitfall
Two traps. First, the false friend: British English has its own “ta”, meaning thanks, and English speakers reflexively read it that way. Uruguayan ta never thanks anyone. Second, do not use it to accept an offer of mate: that circle runs on its own rules, where gracias means you are finished and ta means nothing at all. Argentina and Paraguay say ta too, but nowhere carries as much of a conversation on it as Uruguay does.
