Synonym discussion
Sense: adverb/1
All four words describe actions done according to rules or customs, but they differ in scope. 'Formally' (sense 1) emphasises following established legal or organisational procedures — a contract is formally signed, a complaint is formally lodged. 'Officially' is the closest synonym and is often interchangeable, though it carries a stronger implication of authority or recognition from an institution ('the news was officially confirmed'). 'Properly' is broader and less tied to institutional rules; it can mean 'in the correct way' in everyday contexts ('the children were taught to behave properly'). 'Ceremoniously' is narrower and more dramatic, describing actions performed with deliberate ritual or pageantry ('the flag was ceremoniously raised'). For most official contexts, 'formally' and 'officially' are the best choices. Example: 'The university formally invited the Nobel laureate to speak' — using 'officially' would emphasise the institution's endorsement, while 'ceremoniously' would describe the elaborate welcome.

Etymology
The word 'formally' comes from Middle English 'formalliche', based on the Latin adjective 'formalis' meaning 'relating to form or shape', from 'forma' (form, shape, appearance). The idea of acting according to established 'forms' or procedures gave rise to the official meaning, while the sense of polite, correct behaviour developed alongside it in the 17th century.
