Language Note | Tone
an informal tone is used mainly for writing to friends and in casual situations.
For example, to find information we might say: ‘Tell me about…’
a semi-formal tone is used when we are writing to someone that we do not know very well. The language used is often more polite and respectful than in an informal situation.
Example: ‘I’d like to know about…’
a formal tone should be used in a professional, serious context.
Example: ‘I would be interested in finding out about…’
Note that there isn’t always a clear line between what is informal and what is semi-formal, or what is semi-formal and what is formal. As you read more, you should naturally get a better idea of tone.
