Final answer:
In an informal letter, the receiver should be addressed by their name or an appropriate title. The closure of an informal letter should match the tone of the letter. Informal letters are typically brief and friendly in nature.
Step-by-step explanation:
In an informal letter, the receiver of the letter should be addressed by their name or an appropriate title. A common way to address the receiver in an informal letter is by using their name, for example, 'Dear John'. This creates a friendly and personal tone. It is important to use an appropriate tone and language when writing an informal letter to convey warmth and familiarity.
The closure of an informal letter should also match the tone of the letter. 'Yours faithfully' would not be a suitable closure for an informal letter as it is more commonly used in formal letters. Instead, more suitable closures for informal letters would be 'Warm regards', 'With love', or 'Take care', among others.
Informal letters are typically brief and friendly in nature. They should not be overly lengthy or formal. It is important to keep the content concise and easy to read. However, this does not mean that informal letters cannot include details or personal anecdotes if relevant to the letter's purpose.
