English-Hindi code-switching in marketing copy

In a great deal of ordinary Indian business conversation, two languages occupy one sentence without anybody remarking on it. "Boss, yeh invoice pending hai" is not a failure to speak either language properly; it is how the sentence is actually said, with the structural words in one language and the business vocabulary in another because that is where each is most natural. Marketing copy written in careful monolingual English is therefore written in a register nobody in the room uses.

The argument for letting copy switch is straightforward: matching how your audience speaks reduces the distance between the reader and the message, and that distance is what makes advertising feel like advertising. The argument against is equally straightforward and gets skipped: a switch only works if the reader has both languages. Speech has a safety mechanism that text lacks — a listener who misses a word can ask, or can read it from tone and context in real time. A reader who hits an unfamiliar word in a headline has no recourse and no reason to persist, and you never learn which readers you lost.

The test to apply before switching is whether both languages are genuinely available to essentially all of your intended readers, not most of them. This is a higher bar than it first appears, because the intuition is usually formed from the people around you — colleagues, family, the customers you speak to most — and that sample is systematically unrepresentative of a readership that arrives from search or from a shared link.

Geography is the obvious complication. A business selling across India has readers for whom Hindi is not a second language in any practical sense, and for whom a Hindi word in an English sentence is simply a gap. A business whose customers are all within one region where a language is near-universal is in a genuinely different position, and switching there is a reasonable, low-risk choice. The practical resolution for anyone unsure is asymmetric: switch in the parts where a missed word costs little — an aside, a piece of texture, a closing line — and keep the load-bearing sentences monolingual. A headline, a price, a delivery commitment and a call to action should be readable by every reader you have.

The best reason to switch is that a particular word carries something its translation does not. Some words are more precise, some carry a warmth or a directness the English equivalent has lost, and some name a concept that business English handles only clumsily. Where that is the case the switch is doing real work, and the reader who has both languages gets a sentence that lands better than the monolingual version would.

But it is worth being honest about how often that is actually true. A word like मुनाफा maps closely onto profit, and using it instead is a choice about register and warmth rather than about precision — a legitimate choice, and not one that adds meaning. The failure mode is switching for flavour, where a Hindi word is dropped into otherwise English copy to signal cultural proximity. Readers detect this quickly and it reads as a marketing decision rather than a natural way of speaking, which produces exactly the distance the switch was meant to close. A useful check: if you would not say this sentence this way to a customer in person, it will not read as natural on a page.

Writing Hindi in Devanagari is the correct and complete form, and it makes a hard boundary in the text: a reader who does not read the script gets nothing at all, not even an approximation. It also has practical costs that are easy to miss until they bite — fonts render inconsistently across older devices, text may not survive being copied between systems intact, and search behaviour differs because many people search for Hindi terms typed in Latin characters rather than in the script.

Hindi written in Latin script — Hinglish — genuinely splits the difference, and it is the form most people actually type. A reader who does not know the word can at least sound it out, which sometimes recovers the meaning where a script they cannot read never will. It renders everywhere and matches how people search. What it gives up is correctness and consistency: there is no single agreed spelling for most words, so the same word appears several ways, which looks careless when it accumulates in one document. If you use it, decide the spellings once and write them down, and accept that you are choosing reach over precision — which for marketing copy is usually the right trade.

Some sentences carry consequences if misunderstood, and those should be monolingual in whichever language your whole audience reads. Prices, quantities, dates, delivery commitments, return conditions, anything about payment, and the call to action itself. A reader who misreads a warm aside has lost nothing. A reader who misreads a return window has been misled, and the fact that the ambiguity came from a language choice rather than an intention will not matter to them or to anybody adjudicating it later.

This leads to a simple structural rule that resolves most cases without agonising: switch in the texture, not in the terms. The conversational connective tissue can carry a switched word comfortably; the commitments cannot. It is also worth remembering the readers you cannot see. Screen readers handle mixed-script text unpredictably, and a page whose meaning depends on a switch may be read aloud as nonsense. Automated translation handles it poorly too. Neither is a reason to avoid switching entirely, but both argue for keeping the essential meaning recoverable from the dominant language alone.

The worst outcome is not choosing either approach but having no policy, which is what usually happens: one page switches heavily because the person writing it speaks that way, the next is formal monolingual English, a message thread is Hinglish, and a customer encountering two of them concludes that two different businesses are involved. Inconsistency does more damage than either consistent choice, because consistency is a large part of what makes a small business read as substantial.

So write the decision down, briefly, and make it specific enough to follow: which language leads, whether switching is allowed and where, whether Hindi appears in Devanagari or Latin script, and the agreed spelling of the words you use often. That takes a page and settles a recurring argument. Then be honest about what you cannot know from the inside. You cannot tell how a mixed-language headline reads to somebody outside your immediate circle, and the only way to find out is to ask a few readers who are not colleagues — which is cheap, and considerably more reliable than the confidence of the person who wrote it.
