This is where you mostly use the continuous verb-adjective state tense.
You use the word "lissa" which means "yet" for this purpose
The tool "lissa" itself is a word which means still, and yet and it could be used to represent the perfect tense in English with the other tool/word "khalas"
example: I have just eaten my lunch
in Egyptian: ana lissa wakel ghadaya
ana : I
lissa = yet
wakel = eaten
ghadaya = my lunch
So, here is the rules to follow
pron + "lissa" + negation with past tense if wanted/cont verb-adjective state + noun with poss. pron
ex: ana lissa ma-kalt-sh ghadaya means: I have not yet eaten my lunch.
2nd ex: ana ma-roHt-sh lissa means: I did not go yet. (again depending on the on focus object; here, the person is on focus so he comes first and the time comes later.)
3rd ex: ana lissa meakkelo means I have just made made(m) him to eat. (refer back to the second type of the cont verb-adj state tense)
"khalas" which means Already or Finally can be used the same with "lissa"
These two words are actually tools that describe verb state.
