Sense: adverb/1

All five words add a further point to what has already been said, but they differ in register and weight. 'Additionally' is formal and neutral, common in reports, emails, and academic writing. 'Furthermore' is the most formal and often signals a stronger or more decisive point: 'The plan is expensive; furthermore, it is unsafe.' 'Moreover' is also formal and tends to introduce evidence that supports the previous claim. 'Also' is the everyday neutral choice and fits both speech and writing, but its position inside the sentence is more flexible: 'She also speaks Japanese.' 'Besides' is slightly informal and often suggests the new point is the deciding one: 'I'm tired; besides, it's raining.'

Etymology

LatinOld FrenchMiddle EnglishEnglish

Formed in English in the late 1500s by adding the adverb suffix '-ly' to the adjective 'additional'. 'Additional' itself comes from the Latin verb 'addere', meaning 'to add to' or 'to put toward', built from 'ad-' (to) and 'dare' (to give). The word entered English through Old French 'addicion' before the adjective and adverb forms developed.
