• Stress, Intonation
I down the wrong sound many words that sound will not be smooth.

o Word
o Phrase
o Sentence
I'm talking about grammar mistakes because I sorted the sentences. For example, “ I have four people best friends” (It’s incorrect) I think that “My best friends are Meen, Beam, Por, and Fair.” ( It’s correct more than above sentence.)
