To say that you don't have something in Engpsh, you can use the phrase "I don't have" followed by the name of the thing you don't have. For example:
"I don't have a pen." (Meaning: I don't have a pen.)
"I don't have my phone." (Meaning: I don't have my phone.)
"I don't have any money." (Meaning: I don't have any money.)
You can also use the word "don't" to negate a verb, as in:
"I don't know." (Meaning: I don't know.)
"I don't understand." (Meaning: I don't understand.)
"I don't speak Engpsh." (Meaning: I don't speak Engpsh.)
I hope this helps! Let me know if you have any other questions.
