The Basic Form
You can identify this passive version of פִּעֵל by applying the following rules of thumb:
There is almost always a dot of emphasis – a דָּגֵשׁ – that appears in the second letter of the root. Two exceptions: when the root is composed of four letters (usually a foreign root), and when the second root letter makes a guttural sound, making such emphasis difficult for native speakers to pronounce (such as the letter ע in פֻּעַל).
In the past tense, the three letters of the root appear first in the word, but unlike the קל form, there is almost always a דגש in the second letter of the root, as in הַכֶּסֶף שֻׁלָּם (the money was paid).
In all three major tenses, there is an oo-ah or oh-ah vowel rhyming pattern.
Witness these patterns as you review the chart below, which lays out all the possibilities of the verb מְדֻבָּר (spoken of) in past, present and future tenses:
| ציווי imperative |
עתיד future |
הווה present |
עבר past |
|
| אֲדֻבַּר | מְדֻבָּר, מְדֻבֶּרֶת | דֻּבַּרְתִּי | אני | |
| נְדֻבַּר | מְדֻבָּרִים, מְדֻבָּרוֹת | דֻּבַּרְנוּ | אנחנו | |
| תְּדֻבַּר | מְדֻבָּר | דֻּבַּרְתָּ | אתה | |
| תְּדֻבְּרִי | מְדֻבֶּרֶת | דֻּבַּרְתְּ | את | |
| תְּדֻבְּרוּ | מְדֻבָּרִים | דֻּבַּרְתֶּם | אתם | |
| תְּדֻבְּרוּ | מְדֻבָּרוֹת | דֻּבַּרְתֶּן | אתן | |
| יְדֻבַּר | מְדֻבָּר | דֻּבָּר | הוא | |
| תְּדֻבַּר | מְדֻבֶּרֶת | דֻּבְּרָה | היא | |
| יְדֻבְּרוּ | מְדֻבָּרִים | דֻּבְּרוּ | הם | |
| יְדֻבְּרוּ | מְדֻבָּרוֹת | דֻּבְּרוּ | הן |
As in any spoken language, things that are difficult for native speakers to pronounce get altered. So there will be roots that don’t fit into the neat table of פועל above.
