Brief Explanations:

A letter is often a personal communication. It can be written in a more casual tone compared to an essay (which is academic and formal), a commercial (which is promotional and usually has a set structure for marketing), and a speech (which can be formal depending on the occasion like a political speech). Letters can be between friends, family etc. where the language is more intimate and less formal.
