IPA: /səbˈdʒʌŋkʃən/
KK: /səbˈdʒʌŋkʃən/
A thing that is added or joined to something else, often in a subordinate or secondary manner.
In the sentence, the subjunction provided additional information about the main clause.
Subjunction → It is formed from "sub-" (meaning under or below) and "junctio" (from Latin, meaning joining or connection). The word "subjunction" refers to a joining or connection that is beneath or subordinate to something else.
Think of something that is 'under' ('sub-') another connection or joining ('junctio') — that's why subjunction means a connection that is beneath.
