Two core shapes — perfect and imperfect

The perfect (الماضي) describes completed, usually past, actions: كتب kataba 'he wrote'. The imperfect (المضارع) describes ongoing, habitual, or not-yet-completed actions: يكتب yaktubu 'he writes / is writing'. The imperfect is the perfect stem plus a prefix (and often a suffix).

FormArabicTransliterationEnglish
perfect — heكَتَبَkatabahe wrote
imperfect — heيَكْتُبُyaktubuhe writes / is writing
perfect — sheكَتَبَتْkatabatshe wrote
imperfect — sheتَكْتُبُtaktubushe writes
perfect — IكَتَبْتُkatabtuI wrote
imperfect — IأَكْتُبُaktubuI write

Perfect changes its ending; imperfect changes its prefix. Unvowelled, the I- and she-forms of the past look identical (كتبت) — context decides. This conjugation table shows fully vowelled forms as the course's one labelled exception; everywhere else transliteration follows natural pause form.

The imperfect prefixes — four letters to learn

Only four prefix letters cover every imperfect conjugation: أ a- 'I', ت ta- 'you/she', ي ya- 'he/they', ن na- 'we'. Memorize them as أَتَيَنَ — they never change.

This grammar table shows full citation forms intentionally (labelled exception); elsewhere transliteration follows pause form.

Future — just add سوف or سـ

Future = سوف sawfa or the shorter prefix سـ sa- + imperfect: سوف أكتب / سأكتب 'I will write'. No new conjugations at all.
