شفت شنطة لونها احمر، وصديقتي قالتلي انها بدها ياها.

Here, شفت means I saw.

But in Levantine, شفت can also mean you saw when speaking to one male. The form is ambiguous by itself, so context tells you which meaning is intended.

Because Arabic usually drops subject pronouns when the verb already gives enough information.

So instead of saying أنا شفت, people very often just say شفت. Adding أنا is possible, but it usually adds emphasis or contrast.

Yes. شنطة is a very common everyday word for bag in Levantine and many other dialects.

A more formal Standard Arabic word would be حقيبة, but in normal speech شنطة is extremely common.

لونها is made of:

• لون = color
• ها = her / its, feminine singular

So لونها literally means its color. Here, ها refers back to شنطة, which is a feminine noun.

Because Arabic normally leaves out the verb to be in the present tense.

So لونها احمر literally looks like its color red, but it means its color is red. This is completely normal in Levantine.

Because احمر is describing لون in لونها, not شنطة directly.

• لون is masculine, so the adjective is masculine: احمر
• شنطة is feminine, so if you described the bag directly, you would usually say شنطة حمرا

So there is a difference between:

• شنطة حمرا = a red bag
• شنطة لونها احمر = a bag whose color is red

وصديقتي is:

• و = and
• صديقتي = my female friend

The base word is صديقة. When a noun ending in ة takes a suffix like -ي for my, that ending becomes ت in connected form.

So:

• صديقة = female friend
• صديقتي = my female friend

قالتلي is made of:

• قالت = she said
• لي = to me

So قالتلي means she said to me or she told me.

In casual writing, people often attach them as one word: قالتلي. You may also see قالت لي written as two words. Both are fine.

انها means that she... and introduces the next clause.

Then بدها means she wants. This comes from the Levantine pattern بدّ + pronoun suffix:

• بدّي = I want
• بدّك = you want
• بدّه = he wants
• بدّها = she wants

So انها بدها... means that she wants...

Because ياها is the object pronoun it, referring back to شنطة.

So:

• بدها = she wants
• بدها ياها = she wants it

Since شنطة is feminine, the pronoun is feminine too. In writing, you may also see إياها instead of ياها. Both are used to represent the same idea in colloquial Arabic.
