Where does “preemptively” come from?

I need to work through this etymology chain carefully. Looking at the chain provided: - English preemptively - English preempt - Old English -līċ - Latin -ivus - Proto-Indo-European -iHwós - Proto-Indo-European līg- - Proto-Indo-European ḱóm - Proto-Indo-European ḱóm This chain seems problematic - it jumps from "English preempt" to "Old English -līċ" (a suffix), which doesn't make etymological sense for the word "preempt." The word "preempt" comes from Latin "praemittere" (prae- + mittere), not from Old English -līċ. However, I'm instructed to "state only what the chain supports" and not invent. The chain as given doesn't logically connect to form
