The derivational system Forman gives a page and Bergaño gives a chapter
Bergaño names it by analogy: as Saint Stephen is called protomartyr for being the first martyr, the protocompuesto is the first composition a simple verb admits.
"Hay una partícula para significar multiplicidad, que es man en activa, pan en pasiva."
There is a particle to signify multiplicity: man in the active, pan in the passive.
So his protocompuesto is the maN-/paN- derivation you met in B1 lesson 5 as "nasal assimilation." He adds that Tagalog, Ilocano and Pangasinan grammars follow the same pattern — an early comparative observation.
"Multiplicity" is his gloss for what it adds: repeated, habitual or distributed action, or action on many objects.
B1 lesson 5 gave you three rules. Bergaño gives the whole system.
| aral | → | manaral |
| lucas | → | manlucas |
| namas | → | manamas |
| ngangas | → | mangangas |
Where the particle's n meets the root's n, only one is written. Bergaño states the general principle: "cuando concurren dos letras distintas sólo en número, se capa la una" — when two letters differing only in number meet, one is cut.
He adds that roots in n and ng have very few protocompuestos, so they are not confused with the neutral verbs of ma-.
| batbat | → | mamatbat |
| paco | → | mamaco |
Some m roots keep the whole particle: molmol → manmolmol, malmal → manmalmal.
| gaga | → | mangaga |
| calas | → | mangalas |
| quilahut | → | mangilahut |
Gangosa is his word for the nasal quality. He notes you can equally say that c and q convert to g.
| yaus | → | mañyaus (manyaus) |
| tulac | → | manulac |
These are the complicated ones, and Bergaño works through them carefully.
The basic pattern: the nasal joins, and d and s turn into y.
doloc → mañyoloc
sulat → mañyulat (manyulat)
But there are exceptions in both directions. Some d roots take the particle unchanged:
dali → mandali · dilo → mandilo · dayo → mandayo
And many lose the initial entirely, with n taking its place:
dalao → manalao · dugarug → manugarug
"Siempre que la raíz tenga otra d o s, fuera de la inicial, pierde la primera y en su lugar entra la n."
Whenever the root contains another d or s besides the initial one, the first is lost and n takes its place.
| daldac | → | manaldac |
| dalumdum | → | manalumdum |
| dara | → | manara |
| sadsad | → | manadsad |
| sacsi | → | manacsi |
With one exception he flags himself: dacurac → mañyacurac.
This is a dissimilation rule — the language avoiding two similar consonants in one word — stated in 1736, and it is not in Forman.
Here is the detail that makes this lesson worth the effort.
The protocompuesto's
future is the same letters as its present.
They differ only in stress.
| Tense | Stress falls on | Example |
|---|---|---|
| present | the a of the particle | mánaral |
| future | the verb's penultimate | manáral |
Beginner lesson 1 said stress is phonemic and gave you dápat against dapát. This is the same fact doing grammatical work: an entire tense distinction carried by nothing but where the accent falls.
And it is invisible in the modern orthography, which does not mark accent. A written manaral is ambiguous between "teaches" and "will teach" on the page, and unambiguous in speech.
| B1 lesson 5 (Forman) | This lesson (Bergaño) | |
|---|---|---|
| Environments | 3 (p/b, t/d/s, k/g) | 7, with sub-cases |
| d and s | "become y" | three distinct behaviours plus a dissimilation rule |
| Tense | not discussed | present and future by stress |
| Name | assimilation | protocompuesto |
| Meaning | not glossed | "multiplicity" |
Forman is not wrong; he is compressing. His three rules cover most cases and are the right thing to teach at B1. Bergaño is what you read when the three rules fail.
The point of an advanced tier is not more rules for their own sake. It is knowing where to go when the rule you were taught does not produce the form in front of you.
If B1 lesson 5's method fails on a word, the odds are good it is a d or s root with a second d or s in it — and now you know that.
Do speakers know these rules? Not explicitly, any more than an English speaker can state the rule for the plural -s allomorphs. They apply them perfectly and could not write them down.
Is the stress distinction still alive? Forman does not mention it. That may be change, or it may be that he had no reason to. A question for a speaker.
Why "protocompuesto"? Because it is the first composition a simple verb admits — the entry point to the whole derivational system.
This is the largest single body of Kapampangan grammar available anywhere that modern sources do not cover, and it is the reason the C1 tier exists at all.
