Sinhala grammar has its own set of rules and structures. Here are some fundamental grammar rules in Sinhala: Word Order: Sinhala follows a subject-object-verb (SOV) word order. The subject typically comes first, followed by the object and then the verb. Verb Conjugation: Sinhala verbs change their forms based on tense, aspect, and mood. There are different forms for present, past, and future tenses. Noun Declensions: Nouns in Sinhala can be modified with suffixes to indicate case and number. Common cases include the nominative, accusative, genitive, and dative. Adjective Agreement: Adjectives agree with the gender and number of the noun they modify. Adjective endings change accordingly. Pronouns: Sinhala pronouns vary based on politeness, formality, and number. There are distinct pronouns for addressing individuals respectfully. Question Formation: Questions in Sinhala are often formed by using question particles or question words at the beginning of the sentence. The sentence structure remains similar to declarative sentences. Negation: To create negative sentences, the word "නෑ" (na) is often added before the verb. It negates the action of the verb. Postpositions: Sinhala uses postpositions (words that function like English prepositions but come after the noun) to indicate relationships between nouns and other elements in a sentence. Causative Constructions: Sinhala uses causative verbs to express the idea of causing something to happen. The causative construction involves modifying the verb. Honorifics: Sinhala incorporates honorifics to show respect when addressing or referring to individuals. Polite and formal language is important in Sinhala communication. Remember that these are general rules, and there may be variations in specific contexts or dialects. Additionally, language usage can evolve over time, so contemporary Sinhala may differ from traditional grammar rules.
