user5406: An HTLC is a contract making use of both a hashlock and a timelock. I noticed a discrepancy in what various sources state the abbreviation HTLC is short for. I've found:

"Hashed Timelock Contract" according to the Lightning Network Paper
"Hashed Time Locked Contract" according to BOLT #0
"Hash Time Locked Contract" according to the corresponding Bitcoin Optech topic page

What makes the most sense to be the canonical term? Please add supporting evidence.

user51948: Using "hashed" makes it sound like the contract itself is hashed. Because the contract uses a hash, but is not itself hashed, I would say the H should stand for "hash".
Secondly, because "locked" applies to both the hash and the time components, I'd say it should be a separate word, rather than "timelocked".
Technically, initialisms can omit minor words like conjunctions (there is no standard either way, to the best of my knowledge), so while I haven't seen it used, a sensible meaning could be "Hash and Time Locked Contract." That's my two cents.
