Remove the A, add -iel to the root, and use I-affection on the root vowel.
The only exception is muda-, since the U comes from a long O, and long vowels aren't affected by I-affection.
fara- "hunt" → feriel "having hunted"
brona- "survive" → breniel "having survived"
muda- "labor" → mudiel "having labored"
Add -iel, or delete the -ia and then add -iel. For I-verbs and A-verbs ending in -ia, the sund�mar change the same way. To understand which letter changes into which, you must look back to Eldarin. These vowels, like the I-verbs, will lengthen instead of undergo I-Affection.
For the A-verbs ending in -uia, remove the A, add -el. For -uia, there are no vowel changes.
To help you understand this, I've made a chart of the historical changes to these vowels.
Short Sund�mar | → | Lengthened Sund�mar |
---|---|---|
A | → | Ó |
E/I | → | Í |
O/U | → | Ú |
Y | → | IÚ |
Because the sund�mar of IA-verbs are all I-affected, you need to know what the ancient Eldarin sund�ma of the verb was.
Unlike I-verbs, IA-verbs can have a diphthong, EI, in the place of their sund�ma. This is usually an alternate version of an E, and you'll find that such verbs usually have both forms, such as telia-/teilia- and *medhia-/*meidhia-.
Sindarin | Sund�ma | → | Perfect Participle | English |
---|---|---|---|---|
dag- | A | → | d�giel | having slain |
penia- | A | → | p�niel | having fixed |
teilia- | A | → | t�liel | having played |
heb- | E | → | h�biel | having kept |
tir- | I | → | t�riel | having guarded |
brenia- | O | → | br�niel | having endured |
tog- | U | → | t�giel | having led |
elia- | U | → | �liel | having poured |
yr- | Y | → | i�riel | having ran |
If the verb was made from a compound, only the core root's sund�ma is changed.
Sindarin | Sund�ma | → | Perfect Participle | English |
---|---|---|---|---|
echad- | A | → | ech�diel | having fashioned |
gonedia- | O | → | gon�diel | having counted |
There is no exact equivalent to this form in English, so this will take some explaining. It has several properties:
The closest we have in English to this grammatical form is "having ____."
Although it is tempting because we only have one Sindarin past tense, it isn't used for the conjugation of the past tense. Instead it shows the order of an event in relationship to the main action of the sentence.
Nin adl�giel, ni meria. - Having released me, she/he protects me.
I i�n odul am b�r, t�liel a mellyn �n. - The boy came home, having played with his friends.
