The present paper is an attempt to analyze and discuss some important concepts relating to the conditional conjunctions in Assamese, an Indo-Aryan language spoken primarily in Assam. This study explores the form, function and distribution of conditional conjunctions which are used to describe a condition. Conditional conjunctions enable non-finite forms to express conditionality and temporal circumstances. The study focuses on one important way of introducing the structure of condition in Assamese by suffixation to the verb root. The verb of the dependent clause of a conditional sentence carries the inflectional morpheme as a non-finite form, which is not fully inflected for tense and person. The non-finite forms which are used to indicate the function of conditional marker will be discussed. While discussing the function of conditional conjunction as part of sentence structure, the subject-verb agreement of the dependent clause and the temporal expression of the inflectional form will be examined. Most of the examples in this paper are taken from the author’s own native speakers introspection, but some of the examples were first observed in The CIIL-Lancaster Assamese Corpus.
