Why? Because of n-word? And if yes then how very american of you
fr sounds nothing like the fucking n word
ng- like the ng sound of ing
an,- idk man just get good, a makes an uh sound
in words like thiên nga (swan), still obviously won't sound like the n word as the a makes a sound as in fat (the a)
I am not a native speaker but learning how to pronounce things is pretty easy lmao as long as it sounds vaguely like that, there's this epic thing called the IPA on Wiktionary.
