καί
kaí · conjunction · “and, even, also”
Kai is the most common Greek conjunction — and, also, even. Tiny, but it carries the connective logic of the New Testament and often layers in unexpected emphasis.
Kai is the workhorse word that ties Greek sentences together — “and,” “also,” “even.” It is everywhere, and the New Testament’s argument often turns on it.
Sometimes kai is more than connective — it tightens or intensifies, as in Romans 8:32: God “did not spare his own Son but gave him up for us all; how shall he not also (kai) with him graciously give us all things?” One small word can carry the weight of an entire promise.
Definition: and, also, even, so then, too, etc.; often used in connection (or composition) with other particles or small words
KJV usage: and, also, both, but, even, for, if, or, so, that, then, therefore, when, yet
