Nobody can check your Pali

The charge is ดัดจริต. Affected. Putting it on.

And the reason it is worth taking seriously rather than dismissing is that the people making it are usually right about something — just not about the thing they think they are describing.

Start with what mixing actually requires

Thai-English mixing is not random insertion of English words into Thai sentences. It is rule-governed, and the rules are strict.

Sociolinguists have spent fifty years trying to state them. Shana Poplack’s model proposes two constraints. The free-morpheme constraint holds that a switch cannot occur between a lexical stem and a bound morpheme. The equivalence constraint holds that switches occur only at points where the surface structures of the two languages coincide.

The standard illustration is Spanish and English. “I like you porque eres simpático” is fine, because it obeys the syntax of both. But “the casa white” and “the blanca house” are both impossible — the first breaks English word order, the second breaks Spanish. Bilinguals do not produce them. Not rarely: essentially never.

These models are contested and it matters to say so. There are documented counterexamples in both directions — switches the constraints wrongly forbid, and switches they wrongly permit. Hindi-English speakers routinely produce structures the equivalence constraint rules out.

But across the whole dispute, one conclusion is broadly agreed, and it is the one that answers the question.

Code-switching demonstrates grammatical proficiency at a level equivalent to a monolingual speaker’s competence — rather than reflecting incompetence in either language.

Which is the opposite of what the folk charge assumes. The theory behind ดัดจริต is that the speaker is covering a gap: not good enough at English to speak it, not disciplined enough to speak Thai. The grammar says otherwise. Producing well-formed mixed speech requires you to be running both systems at once, correctly, in real time.

Someone genuinely faking it produces something else — and everyone can hear the difference immediately.

And you have been doing it all along

Here is the part that usually ends the argument, and it is built into the linguistics rather than invented for it.

Poplack’s free-morpheme constraint exists precisely to distinguish code-switching from borrowing. Borrowing operates in the lexicon; switching operates at the level of syntax and utterance construction. They are different processes.

And Thai has borrowed enormously. คอมพิวเตอร์. เช็ค. ฟอร์ม. โอเค. เบรก. แอร์. Nobody has ever been called ดัดจริต for saying คอมพิวเตอร์, because it has been naturalised — Thai phonology has absorbed it, and it is simply a Thai word now.

So the objection is not to English material in Thai speech. Thai speech is full of it and always has been.

The objection is to a zone — words that have not yet been naturalised, used by a speaker the listener has decided is reaching. And the boundary of that zone is not a linguistic fact. It moves, generationally, and it moves in one direction. Words that were affectation twenty years ago are unremarkable now.

The reasons that have nothing to do with status

Two of the standard explanations are simply about the job the words do.

Fishman’s domain model observes that bilingual speakers select a code according to where they are and what they are discussing. Not according to whom they wish to impress. A Thai working in software, finance, medicine or logistics operates in a domain where the vocabulary arrived in English and the Thai equivalents are either descriptive phrases or nonexistent. Research on Thai-English switching in online teaching found exactly this: switching to English technical terminology that has no established Thai equivalent.

And one motivation listed in the literature is straightforwardly practical: a speaker cannot express something adequately in one language, so switches to work around it. That is real, and it applies to everybody, in every bilingual community on earth.

“Deadline” is not a status claim. It is one word standing in for a Thai phrase.

But sometimes it is exactly what you think it is

The article would be dishonest if it stopped there, because the folk charge is not baseless. It is misdirected.

Myers-Scotton’s Markedness Model proposes that speakers choose a code that marks their rights and obligations relative to the others present. Many sociolinguists object that this assumes too much rationality — but nobody disputes that code choice carries social meaning.

Howard Giles’s communication accommodation theory describes speakers converging their speech towards someone whose approval they seek, and diverging to emphasise distance. Peter Auer goes further: code-switching does not merely reflect a social situation, it creates one. And code-switching is understood in the literature to index membership of a social group.

So yes. Language choice can be a status move. That is not a Thai folk prejudice; it is in the textbooks.

What the folk charge gets wrong is the evidence. It treats the linguistic form as proof of the social motive — and the form cannot carry that weight, because the identical form is produced by a doctor reaching for a technical term, an engineer using the vocabulary of her field, and somebody performing sophistication at a dinner table.

You cannot tell which from the sentence. You are inferring it from the speaker.

Which is the actual finding

Notice who never gets accused.

A surgeon saying “CT scan” is not ดัดจริต. A mechanic saying เบรก and คลัตช์ is not ดัดจริต. A programmer saying “deploy” is not ดัดจริต.

The accusation appears when the listener judges that the speaker is claiming a standing they have not established. It is triggered by the perceived gap between the register and the person, not by the number of English words.

Which makes ดัดจริต a judgement about social position, delivered in the grammar of a judgement about language. That is worth knowing, because the two are argued very differently. You can win an argument about someone’s grammar. You cannot win an argument about whether they are entitled to their own manner.

And the thing that changed

Article 151 Every word for rich is borrowed of this collection found that Thai’s native vocabulary describes rank, while every word for wealth is borrowed — เศรษฐี from Sanskrit, เสี่ย traced back through Chinese, the whole apparatus of money words arriving from somewhere else.

Borrowed vocabulary has carried status in Thai for as long as there has been Thai. Pali and Sanskrit for religion, learning and royalty. Khmer for the court register. Chinese for commerce. Using the borrowed word instead of the plain one has always been how a Thai speaker signalled education, refinement or standing.

So the practice is not new at all. What is new is one thing, and it explains the whole complaint.

Nobody could check your Pali.

If you deployed a Sanskrit-derived word to sound learned, the listener had no way to assess whether you had used it well. The prestige language was, for practical purposes, unauditable — which meant the claim it made was unfalsifiable and therefore uncontested.

English is not like that. Every Thai in the room studied it at school for a decade. The listener can hear the accent, notice the misuse, catch the word deployed slightly wrong. For the first time in the history of Thai status-marking, the audience can mark the paper.

ดัดจริต is what a prestige claim sounds like when the audience can check it.

The mixing is not new. The auditing is.

Common misconceptions

“It means their Thai is weak.” Producing well-formed mixed speech requires both grammars running correctly at once. The literature’s agreed conclusion is that it demonstrates proficiency, not its absence.

“It’s random.” It is rule-governed. Bilinguals essentially never produce the forbidden structures, in any language pair.

“Real bilinguals don’t mix.” Mixing is characteristic of bilingual communities everywhere and is one of the most-studied phenomena in sociolinguistics.

“Saying คอมพิวเตอร์ is different.” It is — that is borrowing, which operates in the lexicon. But the boundary between borrowing and switching moves generationally, and it only moves one way.

“So nobody is ever showing off.” Some are. Code choice carries social meaning and the literature says so. The error is treating the sentence as the evidence.
