The Lich
Lic meant "body" in Old English. It had a macron, or dash, over the i to signify a long vowel. It appears in words like "lich-house" for mortuary and "Lych-gate" for roofed gate of a graveyeard, where a corpse awaits burial. This morphed over time into the suffix -ly, which used to be a word by itself, We see it now as in endings of adverbs and some adjectives (clearly, happily, homely, manly). Hope this helps.
