Extended Material with Examples
The Sound and the Weak Verb
The verb is divided, by reference to the type of letters that compose it, into two categories: (a) the sound verb (al-fiʿl al-sahih); (b) the weak verb (al-fiʿl al-muʿtall).
First: The Sound Verb
jalasa
(he sat)
hadara
(he attended)
kataba
(he wrote)
rafaʿa
(he raised)
qaraʾa
(he read)
amara
(he commanded)
samiʿa
(he heard)
The sound verb is in turn divided into three types:
1 — Sound and salim: every verb whose root letters are free of hamza and gemination.
jalasa
(he sat)
hadara
(he attended)
rafaʿa
(he raised)
samiʿa
(he heard)
2 — Sound and mahmuz: every verb in which one of its root letters is a hamza — whether at the beginning, middle, or end of the verb.
akhadha
(he took)
amara
(he commanded)
adhina
(he gave permission)
akala
(he ate)
saʾala
(he asked)
saʾima
(he grew weary of)
daʾaba
(he persisted)
jaʾara
(he cried out)
malaʾa
(he filled)
dharaʾa
(he created)
qaraʾa
(he read)
lajaʾa
(he took refuge)
3 — Sound and mudaʿʿaf — divided into two types:
(a) Triliteral mudaʿʿaf: one in which the middle root letter and the final root letter are of the same kind ('doubled').
madda
(he extended)
ʿadda
(he counted)
sadda
(he blocked)
shadda
(he tightened)
(b) Quadriliteral mudaʿʿaf: one in which the first and third letters are of the same kind, and the second and fourth letters are also of the same kind.
zalzala
(he shook)
waswasa
(he whispered insidiously)
lajlaja
(he stammered)
walwala
(he wailed)
Second: The Weak Verb
wajada
(he found)
qala
(he said)
saʿa
(he strove)
The weak verb is divided into four types:
1 — Mithal: one whose first root letter is a weak letter.
waʿada
(he promised)
wajada
(he found)
walada
(he gave birth)
wasiʿa
(he encompassed)
yabisa
(it dried)
yanaʿa
(it ripened)
yatima
(he became orphaned)
yaʾisa
(he despaired)
It is worth noting that mithal verbs beginning with waw are far more common than those beginning with yaʾ. Some morphologists have counted the verbs beginning with yaʾ as around twenty-four, some of which are rarely used in the language. Here are some for further enrichment:
yafaʿa
(he reached adulthood)
yaqina
(he became certain)
yamina
(he became fortunate)
yasara
(he became easy)
yaqiza
(he became awake)
yaraqa
(it leafed out)
yatana — meaning that the woman gave birth to a baby breech-first. yahata — meaning 'became putrid', as in 'the wound became putrid'. yaqaha — meaning 'he obeyed and was quick'. yaʿara — meaning 'it bleated', as in 'the sheep bleated'. yafakha — meaning 'striking on the crown of the head'. yamama — meaning 'he drowned in the sea'. yadaʿa — meaning 'he dyed'. yalla — meaning 'became short', as in 'the teeth became short'. yarra — meaning 'became hard'.
2 — Ajwaf (Hollow): one whose second root letter is a weak letter.
qala
(he said)
baʿa
(he sold)
nama
(he slept)
sama
(he fasted)
3 — Naqis (Defective): one whose final root letter is a weak letter.
rama
(he threw)
saʿa

4 — Lafif (Compound-Weak): one with two weak letters. It is divided into two types:
(a) Lafif maqrun (joined): one in which two weak letters come together with no sound consonant separating them.
awa
(he took refuge)
shawa
(he roasted)
rawa
(he watered / narrated)
ʿawa
(it howled)
lawa

(b) Lafif mafruq (separated): one with two weak letters that are not adjacent — i.e., a sound consonant comes between them.

(he fulfilled)
