Vereri · Revereri · Venerari · Colere · Observare · Adorare · Admirari · Suspicere

1. Vereri and revereri mean, to feel reverence; whereas venerari, to show reverence. Tac. Ann. xiv. 13; comp. venerationem sui with matris reverentia. 2. Vereri (ὁρᾶν?) denotes respect bordering on fear and bashfulness; whereas revereri, fear and bashfulness arising from respect. In vereri, fear, in revereri, respect is the principal notion: hence verecundia is the dread of exposing one’s self before the person respected; whereas reverentia, the calm consciousness that some one is worthy of this reverential feeling. 3. Venerari (ἄντεσθαι?) is used (at least in Cicero) only for demonstrations of reverence towards the gods and sacred things; observare, only for such demonstrations towards men; colere, towards either. Cic. Rep. i. 12. Ut . . . Africanum ut deum coleret Lælius, domi vicissim Lælium observaret in parentis loco Scipio. And, N. D. i. 42. ii. 28. The venerans seeks only to express due reverence, and by self-humiliation to avert the anger of the gods; the colens (from κόλαξ) seeks by acts of courtesy, of service, and of respect, to win the affection of some one, and the fruits of it, as from a cultivated field. Veneratio shows itself more in prayer; cultus, more in sacrifice: veneratio is more a single, transient act; cultus more a permanent expression of respect. Tac. H. i. 10. Vespasianus . . . Titum filium ad venerationem cultumque (ejus) miserat; that is, that he might do homage to the new emperor, and then also remain in his circle of courtiers. 4. Observare (from ἐρύεσθαι) involves a mere negative notion, and denotes having regard for, in opp. to slighting; yet is not, on this account, colere a stronger, observare a weaker term. Colere, indeed, involves more palpable activity, operam; whereas observare, more tender regard, pietatem; hence sometimes the one, sometimes the other, is the stronger expression. 5. Adorare is the most general expression for any sort of worship; whereas veneratio consists more in gestures, precatio in words. 6. Reveremur validas auctoritates; admiramur raras virtutes; suspicimus excellentia dignitate. At the same time it appears to me, that the reverens is in a state of silent awe; the admirans with the expression of loud, or at least visible enthusiasm; the suspiciens, under the image of one looking up to another with an humble feeling of his own inferiority. Revereri refers especially to moral; admirari, to intellectual and moral; suspicere, to any, even adventitious, pre-eminences. (ii. 185.)
