Synonym discussion
Sense: adverb/1
All five words point to the central nature of something, but they differ in tone and scope. 'Basically' is the most everyday choice and is very common in speech: 'The job is basically about answering emails.' 'Essentially' is a touch more formal and is often preferred in writing: 'The two reports are essentially identical.' 'Fundamentally' goes deeper, suggesting the very root of a thing — used in serious or scientific contexts: 'The two theories are fundamentally different.' 'Mainly' shifts the focus to the largest portion rather than the core nature: 'The class is mainly girls.' 'In essence' is a fixed phrase used in writing to introduce a careful summary: 'In essence, the proposal asks for more time.'

Etymology
Formed in English in the early 1800s by adding the adverb ending '-ally' to the adjective 'basic'. 'Basic' itself comes from the noun 'base' (meaning the lowest or supporting part), which entered English from Old French 'base' and ultimately from Latin 'basis' and Greek 'básis' meaning 'a step' or 'foundation'. The modern conversational use of 'basically' to summarise a point became widespread only in the twentieth century.
