[Conscientious]

peace be upon u friends

i just wanna ask

does any know when we can pronouce the (g ) sound as /dg/ or /g/ a

is there a general rule ? coz i know that there must be exceptions

and the same thing for (th) sound , sometimes we pronounce it as

ث and sometimes as ذ

like in breath (the Noun) and breathe (the Verb)a

i hope to fine an answer soon
