Gee, those quotes seem so old and *COUGH* dusty *cough* (;-). As if the quotes for 'principle' had to be the oldest available, the principal ones. Seriously, those quotes do not help much to understand the meanings, there should exist better ones. Phrases that come to my mind are: "the principle of operation", "in principle". I do not know the intended style of wiktionary yet, so won't edit these in for now.
- This is clearly an old entry, both in Wiktionary terms and in terms of the definitions. It's clearly taken from Webster 1913 and hasn't been put into the style Wiktionary currently uses. You'll get a better feel for Wiktionary by looking at the "N" entries in Special:recent changes. -dmh 19:37, 21 Sep 2004 (UTC)
Fair enough, principal and principle are from the same roots and therefore related. I'll add a Usage Note to call out the principle/principal distinction explicitly. -dmh 02:21, 22 Sep 2004 (UTC)
