grammar, a right-branching sentence is a sentence in which the main subject of the sentence is described first, and is followed by a sequence of modifiers that provide additional information about the subject.
The inverse would be a Left-branching sentence.
The name "right-branching" comes from the English syntax of putting such modifiers to the right of the sentence.
Right-branching sentences are generally held to be easier to read than other similarly-complex grammatical structures in English, perhaps because other branching styles require the listener to hold more information in memory to be able to correctly interpret the sentence.
