及び
And, As well as
Structure
Explanation
The word 及び serves as a conjunction, meaning 'and' or 'as well as'. It is derived from the conjunctive form of the う-Verb 及ぶ, which means 'to reach' or 'to extend to'. While it is often simply translated as 'and', the nuance of 及び is closer to its root verb, suggesting that a list 'extends to include' the following item(s).
As a conjunction, 及び is used to connect nouns or clauses, often appearing between the items it is connecting or at the beginning of a subsequent clause.
