K “open” = anoigo. From ana (up, back, again, among, between, anew) + oigo (to open). This is to open in literal or figurative sense.
L “mouth” = stoma. Perhaps from tomoteros (sharp, keener); from temno (to cut). This is mouth, speech, language, the tip of a sword, an opening in the ground.
M “proclaim” = ereugomai. 1x in NT. This is to burp out, spit, utter, declare.
N “hidden” = krupto. 18x in NT. This is to hide by covering, secret, hidden things. This is the root of the word “cryptography.”
O “foundation” = katabole. Related to “parables” in v34. 11x in NT. From kataballo (to cast down, lay prostate, set a foundation); {from kata (down, against, throughout, among) + ballo (see note E above)}. This is a foundation or a plan for one – setting the foundation according to the plans. Figuratively, it can be the beginning of something, sowing, or conception.
P {untranslated} = kosmos. Some manuscripts add “of the world.” Perhaps from the base of komizo (to carry, convey, recover); from komeo (to take care of). This is order, the world, the universe, including its inhabitants. Literally, this is something that is ordered so it can refer to all creation. It can also refer to decoration in the sense that something is better ordered and, thus, made more beautiful. This is where “cosmos” and “cosmetics” come from.
