Perfect of 3-weak verbs
The verbs, whose dictionary form (3rd, sing., masc.) ends with 讛, are called 3-weak. That 讛 is not a part of the root, thus the root has two letters.
These verbs are declined as shown in the following example with the verb 讘谞讛:
| person | gender | singular | plural |
|---|---|---|---|
| 3rd | masculine | 讘谞讛 | 讘谞讜 |
| feminine | 讘谞转讛 | ||
| 2nd | masculine | 讘谞讬转 | 讘谞讬转诐 |
| feminine | 讘谞讬转谉 | ||
| 1st | 讘谞讬转讬 | 讘谞讬谞讜 |
Imperfect of 3-weak verbs
These verbs are declined as shown in the following example with the verb 讘谞讛:
| person | gender | singular | plural |
|---|---|---|---|
| 3rd | masculine | 讬讘谞讛 | 讬讘谞讜 |
| feminine | 转讘谞讛 | 转讘谞讬谞讛 | |
| 2nd | masculine | 转讘谞讛 | 转讘谞讜 |
| feminine | 转讘谞讬 | 转讘谞讬谞讛 | |
| 1st | 讗讘谞讛 | 谞讘谞讛 |
Note however that in Gen. 1:4 imperfect, 3rd person, sing., masc. of the word 讬专讗 (from 专讗讛) doesn't end with 讛 but the 讛 is omitted.
Active participle of 3-weak verbs
3-weak participles are declined like this:
| singular | plural | |
|---|---|---|
| masculine | 讘谞讛 | 讘谞讬诐 |
| feminine | 讘谞讛 or 讘谞讬讛 | 讘谞讜转 |
Perfect of empty verbs
The verbs having 讜 or 讬 as the second letter in the three-letter root are called empty verbs, because this 讜 or 讬 is omitted in certain grammatical forms. (Some grammarians consider these as having two letter roots. According to Victor Porton, it is more convenient to consider them as three-letter roots because we need to distinguish between 讜 and 讬.)
The perfect of empty words is formed similar to perfect of regular verbs but with two letters (the first and the last letter of the root) instead of the full root.
In imperfect the second letter of the root is not omitted. Before the suffix 谞讛 in imperfect of empty verbs sometimes is added the letter 讬. (WRONG: Sometimes it is omitted in imperfect: Gen. 4:8, word 讜讬拽诐.
In participles of empty verbs the second letter of the root is omitted.
Perfect and imperfect of double verbs
The verbs whose two last letters of the root are identical are called double verbs. In some forms of perfect the last letter is replaced with 讜. An example with perfect of the word 住讘讘 (encircled):
| person | gender | singular | plural |
|---|---|---|---|
| 3rd | masculine | 住讘讘 | 住讘讘讜 |
| feminine | 住讘讘讛 | ||
| 2nd | masculine | 住讘讜转 | 住讘讜转诐 |
| feminine | 住讘讜转谉 | ||
| 1st | 住讘讜转讬 | 住讘讜谞讜 |
Some of double verbs follow the regular declension.
In imperfect of double verbs one of the double letters is omitted.
Imperfect of 1-谞
For 1-谞 verbs the letter 谞 is omitted after prefixes in imperfect (not always).
谞 is also sometimes omitted in imperative of 1-谞 verbs.
In infinitive or these verbs the first 谞 in the root is omitted and added 转 after the root.
Some of the verbs 1-讬 are declined in the same way as 1-谞.
Imperfect of 1-讗 verbs
In the first person, singular of 1-讗 (having 讗 as the first letter of the root) verbs that 讗 is omitted (so leaving only one 讗 instead of two consecutive 讗讗).
Sometimes 讗 is omitted in other imperfect forms (see Gesenius), specifially after letter Yod.
Imperfect of 1-讬 verbs
The Yod is omitted in some forms for some of these verbs. (TODO: Specify exactly.)
Other irregular verbs
Aleph on both second and third position is sometimes omitted in verbs and participles (Gesenius).
