IPA: /səˈbɔːrdɪneɪtə/
KK: /səˈbɔrdəˌneɪtər/
A word that connects a dependent clause to an independent clause, showing the relationship between them.
In the sentence 'Although it was raining, we went for a walk', the word 'although' is a subordinator.
Subordinator → It is formed from "sub-" (meaning under or below) and "ordinare" (meaning to arrange or order). The word "subordinator" refers to a word or phrase that arranges or places something under another in a sentence, typically a subordinate clause.
Think of something that is 'under' ('sub-') another thing in terms of 'arranging' ('ordinare') — that's why a subordinator is a word that places one idea under another.
