The 'To Be' Verb in Odia: Achi, Heuchi, Thila

Try translating "the train is at the platform" into Odia and you'll hit something unexpected: the verb you need isn't the same "to be" you'd use to say "she is a doctor." In fact, for that second sentence, present-tense Odia doesn't use a visible "to be" verb at all. There are three distinct grammatical situations where English speakers reach for "is" or "was" — and Odia handles each of them differently. Getting this right is what separates sentences that sound structurally sound from sentences that a native speaker quietly adjusts in their head before responding.

What "to be" actually means: three jobs, not one

English's "to be" does so many things we stop noticing: it expresses existence ("there is a temple here"), equates two concepts ("Puri is a city"), ascribes states ("she is hungry"), and marks ongoing action ("he is eating"). Odia distributes these functions across separate forms, and the split between existence and equation is the most important distinction to understand.

The three core situations:

Existential — something or someone exists, or is located somewhere. ଅଛି (achi) handles this in the present.
Equative/predicative — one thing is identified as another, or assigned a property. The present tense drops the copula entirely.
Past — both existential and equative past use ଥିଲା (thilā, "was").

This three-way split has immediate practical consequences. Mis-applying one where another belongs is the most recognizable "to be" error English speakers make in Odia.

ଅଛି (achi): the existential present

Achi is the first form you need. It means "exists," "is present," or "is located at." When you want to say something is somewhere, or simply that it exists, achi is the verb.

Odia	Romanization	English
ଏଠି ଏକ ମନ୍ଦିର ଅଛି	eṭhi eka mandira achi	There is a temple here
ତୁ ଘରେ ଅଛୁ	tu ghare achu	You (intimate) are at home
ମୁଁ ଅଛି	muṁ achi	I am here / I exist
ଟ୍ରେନ ପ୍ଲାଟଫର୍ମରେ ଅଛି	ṭrena plāṭapharmere achi	The train is at the platform

The form achi is technically the third-person form, but in colloquial Odia it appears widely in first- and second-person contexts too, especially in short affirmative statements. The full conjugation adjusts for person and formality register:

Person	Odia	Romanization	English
ମୁଁ (muṁ — I)	ମୁଁ ଅଛି	muṁ achi	I am (here/present)
ଆମେ (āme — we)	ଆମେ ଅଛୁ	āme achu	we are
ସେ (se — he/she)	ସେ ଅଛି	se achi	he/she is (here)
ସେମାନେ (semāne — they)	ସେମାନେ ଅଛନ୍ତି	semāne achanti	they are
ତୁ (tu — intimate you)	ତୁ ଅଛୁ	tu achu	you are (intimate)
ତୁମେ (tume — neutral you)	ତୁମେ ଅଛ	tume acha	you are (neutral)
ଆପଣ (āpaṇa — formal you)	ଆପଣ ଅଛନ୍ତି	āpaṇa achanti	you are (formal)

Notice the familiar pattern: the formal register with āpaṇa takes the -nti ending, exactly as Odia's three-tier pronoun system predicts throughout the verb system. The intimate tu takes -u. The first-person and third-person singular share achi in practice.

A useful context to anchor this: ଜଗନ୍ନାଥ ଏଠି ଅଛନ୍ତି (jagannātha eṭhi achanti) — "Jagannath is here." In temple language, the deity is addressed with the formal -nti ending, which is why you hear this exact phrase at Puri in the high-formal register.

Equative sentences: where the copula disappears

Here is where Odia surprises English speakers most. In present-tense equative sentences — where you're identifying something as something else, or describing it with an adjective — the verb "is" simply doesn't appear. It's a zero copula.

Odia	Romanization	English
ସେ ଡାକ୍ତର	se ḍāktara	She is a doctor
ଏହା ଭଲ	ehā bhala	This is good
ପୁରୀ ଏକ ସହର	purī eka sahara	Puri is a city
ଆକାଶ ନୀଳ	ākāśa nīḷa	The sky is blue

No verb form at all. "She is a doctor" is literally se ḍāktara — "she doctor." This is grammatically complete and entirely standard. Adding achi here would be a mistake, because achi would imply she is physically present at some location, not that she holds the identity of "doctor."

The practical test: if you could replace "is" with "exists as" or "is located at," use achi. If the sentence is defining, classifying, or describing with a noun or adjective complement — drop the verb entirely.

ସ୍ୱାମୀ ବଘୁଣ ଡାକ୍ତର ଅଛି।

svāmī baghuṇa ḍāktara achi.

"The doctor/husband is present/here." (existential — he's at the clinic today)

ସ୍ୱାମୀ ଡାକ୍ତର।

svāmī ḍāktara.

"My husband is a doctor." (equative — his profession)

The two sentences look nearly identical but mean structurally different things. The first says he's at a location; the second identifies his profession.

ହେଉଛି (heuchi): the continuous "becoming/being"

There's a middle-ground form worth knowing: ହେଉଛି (heuchi), from the verb ହେବା (hebā, "to become" or "to happen"). It describes ongoing states and processes where something is in the process of being or becoming.

Odia	Romanization	English
ଗୁଡ଼ ଗରମ ହେଉଛି	guṛa garama heuchi	The jaggery is getting hot
ଆଜି ବର୍ଷା ହେଉଛି	āji barṣā heuchi	It is raining today
ଦୋକାନ ଖୋଲା ହେଉଛି	dukāna kholā heuchi	The shop is being opened

Heuchi is the present continuous form of hebā — it marks active process rather than static state. Rain falling is a process; the sky being blue is a state. The distinction matters more in some contexts than others, but it explains why you'll hear heuchi in weather sentences and not simple achi.

ଥିଲା (thilā): the past "was"

For past-tense "to be" — both existential and equative — Odia uses ଥିଲା (thilā, "was"). This is one of the most important words in the grammar. It appears in past states, past locations, and the past perfect construction. Once you recognize its thil- core, you start seeing it everywhere.

Full past conjugation:

Person	Odia	Romanization	English
ମୁଁ	ମୁଁ ଥିଲି	muṁ thili	I was
ଆମେ	ଆମେ ଥିଲୁ	āme thilu	we were
ସେ	ସେ ଥିଲ	se thila	he/she was
ସେମାନେ	ସେମାନେ ଥିଲେ	semāne thile	they were
ତୁ	ତୁ ଥିଲୁ	tu thilu	you were (intimate)
ତୁମେ	ତୁମେ ଥିଲ	tume thila	you were (neutral)
ଆପଣ	ଆପଣ ଥିଲେ	āpaṇa thile	you were (formal)

Thilā works for both the existential and equative past:

Odia	Romanization	English
ସେ ଏଠି ଥିଲ	se eṭhi thila	He was here (existential past)
ସେ ଡାକ୍ତର ଥିଲ	se ḍāktara thila	He was a doctor (equative past)
ଆବହାୱା ଭଲ ଥିଲ	ābahāwā bhala thila	The weather was good
ମୁଁ ପୁରୀରେ ଥିଲି	muṁ purīre thili	I was in Puri

The verb form itself shows the agglutinative logic that runs through Odia tenses: thil- is the past existence root, and person markers attach to it directly. You'll also see thilā embedded in larger verb chains: khaithilā ("had eaten"), karuthilā ("was doing") — the thil- core always signals past state.

ହେବ (heba) and ରହିବ (rahiba): future "will be"

Two future forms address different shades of meaning.

ହେବ (heba, "will be / will happen") is the general future of hebā:

Odia	Romanization	English
ସେ ଡାକ୍ତର ହେବ	se ḍāktara heba	He will be a doctor
ଆବହାୱା ଭଲ ହେବ	ābahāwā bhala heba	The weather will be good
ଆଜି ବୃଷ୍ଟି ହେବ	āji bṛṣṭi heba	It will rain today

ରହିବ (rahiba, "will remain / will stay") comes from ରହିବା (rahibā, "to stay, to remain"). It expresses future existence with a sense of continuity — not just that something will be, but that it will persist.

Odia	Romanization	English
ମୁଁ ଏଠି ରହିବି	muṁ eṭhi rahibi	I will stay here
ସେ ଘରେ ରହିବ	se ghare rahiba	He will remain at home
ସ୍ମୃତି ରହିବ	smṛti rahiba	The memory will remain

The choice between heba and rahiba tracks the difference between "becoming" and "continuing." A sentence about what someone will turn into — a teacher, a success, a problem — uses heba. Persistence in a place or state calls for rahiba. In colloquial speech the distinction blurs, but in careful Odia (and in writing) it holds.

Negation: two negators, two different jobs

The same nāhiṁ / nuhaṁ distinction that governs all Odia negation applies here — but the "to be" context makes it unusually clear.

ନାହିଁ (nāhiṁ) negates existential sentences:

Odia	Romanization	English
ଏଠି ଦୋକାନ ନାହିଁ	eṭhi dukāna nāhiṁ	There is no shop here
ସେ ଘରେ ନାହିଁ	se ghare nāhiṁ	He is not at home
ଖାଦ୍ୟ ନାହିଁ	khādya nāhiṁ	There is no food

ନୁହଁ (nuhaṁ) negates equative sentences — whenever "is" links two things as identity or classification:

Odia	Romanization	English
ସେ ଡାକ୍ତର ନୁହଁ	se ḍāktara nuhaṁ	She is not a doctor
ଏହା ଭଲ ନୁହଁ	ehā bhala nuhaṁ	This is not good
ପୁରୀ ରାଜଧାନୀ ନୁହଁ	purī rājadhānī nuhaṁ	Puri is not the capital

The underlying logic: nāhiṁ negates the existence verb achi (or implicitly fills its place). Nuhaṁ supplies the equative copula plus its own negation — it means "is not" as a single unit, because the positive equative sentence has no overt verb to negate. As the Odia negation guide explains in detail, using nāhiṁ in an equative sentence makes it sound as though you're negating a verb that isn't there.

The clearest test: can you add "physically present" to the sentence and have it still make sense? He is not physically present → nāhiṁ. He is not [identified as] a doctor → nuhaṁ.

What this reveals about Odia's grammatical logic

The "to be" system in Odia isn't arbitrary — it reflects a principled distinction between existence and identity that the language encodes more precisely than English does. English uses one word ("is") for both; Odia uses different forms for each, and drops the form entirely when it's purely equative.

For learners, the path through this system is: master the existential achi first, since you'll use it constantly for location sentences. Learn to leave the copula out of present-tense identity sentences — the blank is correct, not an error. Then add thilā for the past, which consolidates both existential and equative past into one table. The futures (heba and rahiba) are the last layer, and the distinction between them is learnable in context.

One final observation worth noting: since Odia verbs don't conjugate for gender, the "to be" forms above are identical regardless of whether the subject is male or female. Se achi means both "he is here" and "she is here." The verb form never changes based on biological sex — a simplification that makes this entire paradigm considerably more manageable than its Hindi equivalent, where hai, hūṁ, ho, haiṁ interact with gender-marked past participles.
