‘Mechanics’ of language in speaking skills includes ________.

The correct answer is pronunciation, grammar and vocabulary.

Speaking skills in any language involve three key areas of knowledge and skill:

1. Mechanics (Language Structure): Using the right words in the correct order with correct pronunciation. This involves understanding and applying $\text{pronunciation}$, $\text{grammar}$, and $\text{vocabulary}$ so that speech is clear and intelligible.

2. Functions (Transaction and Interaction): Knowing how to convey precise meaning or intent (e.g., asking for information, expressing greetings, or clarifying a message).

3. Social and Cultural Rules (Pragmatics): Understanding who is speaking to whom, in what environment, for what reason, and applying social conventions appropriate to the context.

Therefore, the 'mechanics' of language in speaking skills specifically includes pronunciation, grammar and vocabulary.
