I propose a short reference book on verbs with the second root letter Y or W".
Further I designate:
‘k’ - Y or W
‘r’ - a consonant situated to its right
‘l’ - a consonant situated to its left
‘LV’ - a long vocal
‘SV’ - a short
‘o’ - any vocal

1. lokor—> lâr
2. lkûr —> lûr / lâr / lîr
3. lukir —> lîr
4. likâr —> liyâr (k = W)
5. LV —>—> [SV]

On the left side of the equations (1…4) I’ve typed down imaginary combination of sounds, normal for regular verbs. On the right side of these equations there are real combinations.
The bottom equation represents the secondary transformation, carried out after the primary transformation, expressed by the equations (1…4):
A long sound, if cloed in a close syllable, gets short.

6. 2k—> 2k

8. kLV—> kLV

In the models, which require doubling of the middle letters, irregular verbs behave like regular ones (6). So are the verbs with pre- or postposition of along vocal (6 & 7).

It is useful to remember 4 models for verb derivates.

9. participle I - pâIil
10. masdar IV - ifâlah
11. masdar X - isthifâlah
12. local / temporal names - mafâl / mafîl

How does help the reference book to solve WS’s problem ?
1. What is urîdu ?
2. u- witnesses about Imperfect Ind. IV 1s.
3. The corresponding model for regular verbs: uf’ilu
4. The equation 2 confirms this guess.
5. The letter ‘î’ indicates the middle root letter Y.
6. Also, the root is R. Y. D. or R. W. D.
7. How to find the dictionary form ? See equation 1. Râda !
8. I’m searching… But what did I revel ? There’s not neither R. Y. D., nor ‘râda’. There is R. W. D., but it does not include ‘râda’??? At least, there’s ‘arâda’ (to be going, to wish, to want).
Regards.
N.B. What is ‘fusha’, WS ?
