Editing Defective verb (section)

== Arabic ==
In [[Arabic]], defective verbs are called {{lang|ar|أفعال جامدة}} {{Transliteration|ar|ʾafʿāl jāmidah}} (lit., {{gloss|solid verbs}}). These verbs do not change tense, nor do they form related nouns. A famous example is the verb {{lang|ar|[[wikt:ليس|لَيْسَ⁩]]}} {{Transliteration|ar|laysa}} {{gloss|it is not}}, though it is not the only auxiliary verb that exhibits this property. Some Arabic grammarians argue that {{lang|ar|[[wikt:دام#Arabic|دَامَ⁩]]}} {{Transliteration|ar|dāma}} (as an auxiliary verb) is also completely defective; those who dispute this claim still consider it partially defective. Some other partially defective verbs are {{lang|ar|[[wikt:فتئ|فَتِئَ⁩]]}} {{Transliteration|ar|fatiʔa}} and {{lang|ar|[[wikt:زال|زَالَ⁩]]}} {{Transliteration|ar|zāla}}, which have neither an imperative form nor an infinitive form when used as auxiliary verbs.
