secondly

Synonym discussion
Sense: adverb/1
These words all help structure an argument, but each has a different role. 'Firstly' and 'secondly' are parallel discourse markers that explicitly number points — you use 'firstly' to open and 'secondly' to follow. 'Second' works as an informal adverb ('First, ... Second, ...') but is less common in formal writing. 'Next' simply means 'after this' and does not guarantee that the speaker is counting items — it could be the third or fourth point. 'Furthermore' adds supporting information but does not indicate position in a list. For example: 'The hotel was dirty. Furthermore, the staff were rude.' — this adds a complaint but does not label it as the second point. If you want to be precise about ordering, use 'firstly … secondly …'.

Etymology
Formed from the ordinal number 'second' (from Latin 'secundus', meaning 'following' or 'next') plus the adverb-forming suffix '-ly'. The word 'secondly' appeared in English around the 1500s as writers began to use numbered discourse markers to organise longer arguments.
