He did it, she did it

Compare -a for he with -at for she across all five verbs.

The idea

For he, use the base form: kataba. For she, use katabat. Notice the order: katabat (she wrote) is different from katabta (you wrote, to one male). In katabat, the a comes before the final t.

كَتَبَ

kataba — he wrote

huwa — he

-a is the he form used to name the verb.

كَتَبَ

kataba — he wrote

hiya — she

-at marks she: the t closes the syllable. Do not confuse -at with -ta (you, male).

كَتَبَتْ

katabat — she wrote
