Common errors and how to avoid them

Error 1Omitting the closer

The problem: English often drops "that" and never requires a closer. Learners carry this habit into Phi.

Wrong:

*mia tha shia to wepu shelomu
1SG DECL.COMP 3SG PST go understand

Right:

Why it matters: Without tho, the listener cannot know where the embedded clause ends. Is wepu shelomu a compound verb? Does shelomu belong to the embedded clause or the main clause?

How to avoid: - Always pair tha with tho, pha with pho, sha with sho - When you say an opener, mentally commit to its closer - Practice: count your openers, count your closers, they must match

Error 2Putting the closer in the wrong position

The problem: The closer must immediately follow the last word of the embedded clause, before the main verb.

Wrong:

*mia tha shia to wepu shelomu tho
1SG DECL.COMP 3SG PST go understand DECL.COMP.CLOSE

Right:

Why it matters: The closer marks the boundary. If it comes after the main verb, the structure is unparseable.

How to avoid: - Remember: CLOSER then MAIN VERB - The embedded clause's verb comes first, then the closer, then the main verb - Pattern: tha [... embedded-verb] tho main-verb

Error 3Adding a closer after whu

The problem: Learners who have learned that complementizers need closers may borrow one for whu.

Wrong:

*whu nophi kealo tho miona
REL story create DECL.COMP.CLOSE person

Right:

Why it matters: whu has no closer, and no other frame will lend it one. tho ends a declarative frame and nothing else, so it cannot stand here. The head noun is what closes a relative clause.

How to avoid: - Remember: whu is pre-nominal, not pre-verbal - The noun itself is the boundary - No closer needed, no closer exists

Error 4Using English word order

The problem: English puts embedded clauses after the verb. Learners may do the same in Phi.

Wrong:

*mia shelomu tha shia to wepu tho
1SG understand DECL.COMP 3SG PST go DECL.COMP.CLOSE

Right:

Why it matters: Phi is strictly SOV. The embedded clause is the object, and objects come before the main verb.

How to avoid: - Embedded clauses are objects - Objects come before verbs in Phi - Pattern: Subject + tha [clause] tho + Verb

Error 5Confusing tha/tho with sha/sho

The problem: Both involve reported speech, but they serve different functions.

Says something else (quotation instead of content):

This is grammatical, but it claims those were the exact words spoken.

When you meant:

The difference: In the quotation, thia is the original speaker's word, so it refers to whoever they were addressing. In the content report, thia is the reporter's word, referring to the current addressee.

How to avoid: - Ask: Am I preserving exact words? Use sha/sho. - Ask: Am I conveying meaning? Use tha/tho. - Check pronouns: Should they stay as originally spoken, or shift?

Error 6Confusing pha/pho with wa

The problem: Both involve questions, but they serve different functions.

Wrong (using embedded question for direct question):

*pha thia wepu pho
INT.COMP 2SG go INT.COMP.CLOSE
(incomplete, no main verb)

When you meant:

Wrong (using direct question for embedded question):

*mia wa shia wepu phaelo
1SG Q 3SG go feel
(grammatically confused)

When you meant:

How to avoid: - wa is for direct questions expecting an answer - pha/pho embeds questions inside larger sentences - Ask: Is this a question to someone, or a question in my mind?

Error 7Confusing pha/pho with lu

The problem: Both involve conditionality or possibility, but differently.

Grammatical, but not a conditional:

When you meant:

The difference: - pha/pho embeds a question: "I wonder whether X" - lu frames a condition: "If X, then Y"

How to avoid: - Is there a consequence? Use lu. - Is there uncertainty being considered? Use pha/pho.

Error 8Mismatched nesting

The problem: With nested embeddings, closers must match in the correct order.

Wrong:

*mia tha thia pha shia wepu tho pho shelomu
(closers in wrong order)

Right:

How to avoid: - Think of openers and closers like parentheses: ( [ ] ) not ( [ ) ] - The most recently opened clause is closed first - Each type closes its own type: pha with pho, tha with tho

Error 9Forgetting the embedded clause's verb

The problem: Learners sometimes omit the verb inside the embedded clause.

Wrong:

*mia tha shia towe tho sano
1SG DECL.COMP 3SG well DECL.COMP.CLOSE know

Right:

Why it matters: The embedded clause needs to be a complete clause. With predicative adjectives, the copula nai is required.

How to avoid: - Check: Does my embedded clause have a verb? - Remember: towe nai (is well), not just towe (well)

Error 10Double-marking questions

The problem: Using both wa and pha/pho for the same question.

Wrong:

*mia pha wa shia wepu pho phaelo
1SG INT.COMP Q 3SG go INT.COMP.CLOSE feel

Right:

Why it matters: pha/pho already marks the clause as a question. Adding wa is redundant and confusing.

How to avoid: - pha/pho contains the question-marking function - Do not add wa inside pha/pho clauses - Exception: When quoting a direct question with sha/sho, the wa is part of the quoted material

Error 11Wrapping a content question in pha/pho

The problem: English uses "whether" for yes/no questions and moves who/what/where to the front. Learners who have just mastered the frame sometimes wrap it around every embedded question.

Wrong:

*mia pha sua to shua pho sano
1SG INT.COMP who PST come INT.COMP.CLOSE know

Right:

Why it matters: A content question already carries its signal. The interrogative word stands where the unknown element would stand, and that placement alone marks the clause as a question. The frame would mark it twice.

How to avoid: - pha/pho embeds yes/no questions only - If the embedded clause contains sua, hina, kua, or another gap-word, embed it bare

Error 12Leaving the frame verb without its tense

The problem: The embedded clause and the main clause each carry their own time. Learners mark the inner clause carefully and forget the outer verb.

Says something else (present saying instead of past):

When you meant:

Why it matters: An unmarked verb is present. The leaving and the saying are separate events with separate times: the to inside the frame marks the leaving, and only a second to after the closer marks the saying.

How to avoid: - After the closer, ask when the knowing, saying, or asking itself happened - Slot 1 marking for the main verb stands between the closer and that verb

13Self-correction checklist

When you produce an embedded clause, verify:

1. Opener present? Did I begin with tha, pha, or sha?

2. Closer present? Did I add tho, pho, or sho?

3. Closer in right position? Does it come after the embedded verb, before the main verb?

4. Types match? Does each opener match its own closer type?

5. Nesting correct? If multiple embeddings, do closers match in reverse order?

6. No closer after whu? Relative clauses don't have closers.

7. Embedded clause complete? Does it have a subject and verb?

8. Right complementizer type? Am I using the appropriate one for my meaning?

9. Content question? Then no frame; the gap-word already marks it.

10. Frame verb timed? Did the main verb get its own tense after the closer?

14Practice recovery

When you make an error mid-sentence:

Option 1: Restart

*mia tha shia to wepu... mia tha shia to wepu tho shelomu
(abandon the false start, then say the whole sentence correctly)

Option 2: Rephrase

*mia tha shia to wepu shelomu... shorela mia tha shia to wepu tho shelomu
(catch the missing closer, then offer the repaired sentence with REPH: "in other words...")

Option 3: Simplify

*mia tha shia to wepu... shia to wepu. mia shelomu
(break into simpler sentences: "They left. I understand.")

Native speakers of any language self-correct. It is natural and communicative. The goal is understanding, not perfection.

15Summary

Most errors come from English interference: - Omitting closers (English drops "that") - Wrong word order (English is SVO) - Confusing complementizer types (English is less systematic)

With practice, the Phi system becomes intuitive. The regularity helps: once you learn the pattern, it applies consistently.

Core rules to internalize: 1. Every tha needs tho; every pha needs pho; every sha needs sho 2. whu needs no closer 3. Closer comes after embedded verb, before main verb 4. Closers match openers in reverse nesting order 5. A content question embeds bare; its gap-word never takes the frame 6. Each clause carries its own tense, the frame verb included

None of these errors survives the habit of counting: openers on one hand, closers on the other, until the hands match.
