Use of Auxiliary in Hindi

Primary role:

Tense/Aspect anchoring

Auxiliaries license tense/aspect anchoring. Finite clauses in Hindi need an auxiliary (hai, thā, hogā, etc.). That auxiliary anchors tense/aspect (present, past, future, progressive, perfective, etc.).

Without it, sentences like:

  • rām caltā
  • rām nahī̃ caltā

feel incomplete, almost like a nominal predicate or a fragment.


2. Secondary role:

Licensing negation

Auxiliaries also license negation.

Example:

  • rām nahī̃ chaltā hai → grammatical
  • rām nahī̃ chaltā → ungrammatical (clause collapses)

Here, nahī̃ is targeting chaltā. But without hai, the clause cannot close off properly. The auxiliary provides the tense/aspect frame that lets negation scope over a full proposition.

So, auxiliaries don’t create negation. They make space for it by supplying clausal scaffolding.
That’s why the literature often says “auxiliaries license negation” — it’s shorthand for:

Negation needs a finite clause, and auxiliaries are what make the clause finite.


Summary

  • Without auxiliary → fragment, predicate-only, non-finite
  • With auxiliary → full clause, finite, truth-evaluable

FAQ

Q: What is a nominal predicate?
A nominal predicate = a predicate made of a noun or adjective (not a verb).

In Hindi, predicates can be formed from:

  • Verbsrām caltā hai “Ram walks” (verbal predicate)
  • Adjectivesrām bīmār hai “Ram is sick” (adjectival predicate)
  • Nounsrām ācārya hai “Ram is a teacher” (nominal predicate)
