'Mechanics' of language in speaking skills includes ________.

The 'mechanics' of speaking refers to the technical building blocks of spoken language: pronunciation (sound production), grammar (sentence structure), and vocabulary (word knowledge). These are the mechanical components that must be controlled to produce intelligible speech. Clarity of message relates to function, social/cultural rules relate to sociolinguistic competence (pragmatics), and script-words-sentences relates more to writing mechanics. For speaking, pronunciation-grammar-vocabulary are the mechanics.
