"Ja!" is a store brand in Germany (means Yes! but you knew that). Thank you for the terminology so I can look it up.
So far, what I have found is it helps show the difference between words spelled the same but with different meanings. Does it also change the sound of these words from each other?
Ha! Já tens um mini? (Amigos da Quinta) is on the front of the store flyer next to me too. :)
And now, 9 months later I tell you that the "d" is a "d" in Portugal, but if it makes you feel any better they do not pronounce the "e" at the end of words much (very abbreviated, swallowed even). :)
That "gee" sound on Duolingo still throws me off my language game to this day.
And I still do not fully understand why there is an accent on a one syllable word... :D But, this is what I get from one site:
They have a phonetic autonomy, being pronounced strongly in the phrase where they appear.
