-Some verbs don't take an <InlinePs opts={opts} ps={grammarUnits.ooPrefix} /> prefix because they have little particles in the front like <InlinePs opts={opts} ps={{ p: "کې", f: "ke" }} />, <InlinePs opts={opts} ps={{ p: "پرې", f: "pre" }} />, <InlinePs opts={opts} ps={{ p: "بو", f: "bo" }} />, or <InlinePs opts={opts} ps={{ p: "څم", f: "tsam" }} />. These little particles split away from the verb in the perfective aspect just like the <InlinePs opts={opts} ps={grammarUnits.ooPrefix} /> would in other verbs.
+Some verbs don't take an <InlinePs opts={opts} ps={grammarUnits.ooPrefix} /> prefix. Instead, on the perfective side they just shift the accent up to the first syllable. The first syllable also splits off the front, just like the <InlinePs opts={opts} ps={{ p: "و", f: "óo" }} /> would.
 
-Even though we can't add a <InlinePs opts={opts} ps={grammarUnits.ooPrefix} /> prefix, we still have to shift the accent to the front of the root/stem in the perfective aspect.

+It's super important to remember that even though we can't add a <InlinePs opts={opts} ps={grammarUnits.ooPrefix} /> prefix, we still have to shift the accent to the front of the root/stem in the perfective aspect.
 
 Notice how the only difference between the imperfective and perfective aspects is where the emphasis falls. The accent totally changes the meaning of the verb form! 🤯

+## The past participle
+
+There's one more element we need to add to the verb tree: **the past participle**. The past particple is used for making perfect verb forms, adjectival verbs etc. We put this at the bottom in the middle because **it doesn't fit into either aspect** and is seperate from the perfective/imperfective divide.
+
+In almost all verbs, the past participle is just the imperfective root plus a <InlinePs opts={opts} ps={{ p: "ی", f: "ey" }} /> tail that inflects. The <InlinePs opts={opts} ps={{ p: "کول", f: "kawul" }} /> and <InlinePs opts={opts} ps={{ p: "کېدل", f: "kedul" }} /> verbs are the only ones that have irregular past participles.
