The "luke" in lukewarm is a fossilized adjective meaning "tepid, moderately warm" โ so *lukewarm* is actually a pleonasm, like "PIN number." The standalone word *luke* just meant "warmish." Adding *warm* was redundant, but the compound stuck while the root died.
## The chain
| Period | Form | Meaning |
|--------|------|---------|
| Proto-Germanic | *\*khlewaz* | warm, sunny |
| Old English | *hlฤow* / *hlฤowe* | warm, sheltered |
| Middle English (c. 1200) | *luke* / *lew* | tepid, moderately warm |
| Late 14th c. | *luke-warm* | tepid (redundant compound) |
| End of 15th c. | *luke* โ extinct | only the compound survives |
The most likely ancestor is OE *hlฤow* ("warm, sunny, sheltered"), the same root as *lee* and *leeward*. The *h-* dropped off, the vowel shifted, and by Middle English you got *luke* / *lew*. [etymonline.com](

## What else *luke* used to do
Before it vanished, it formed other compounds that also died:
- **luke-hearted** (c. 1500) โ half-hearted
- **luke-hot** (late 14th c.) โ a contradiction, since *luke* already meant "not hot"
- **lew-warm** โ a parallel variant that survived in some dialects longer
The figurative sense ("lacking zeal, indifferent") dates to the 1520s. Thomas More's *Four Last Things* (~1522) has the earliest OED citation, riffing on Revelation 3:16: *"Thou arte neyther hote nor cold but luke warme."* [grammarphobia.com](

## The proper name Luke
Unrelated. That's a contraction of Latin *Lucanus* ("of Lucania"), a region in southern Italy. [saturdayeveningpost.com](

So the word isn't a person's name at all โ it's just an old Germanic root for "sheltered/warm" that got chopped up, lost its *h-* and *ฤ*, and survived only inside the compound that made it redundant.
