optanomai op-tan'-om-ahee, a (middle voice) prolonged form of the primary (middle voice) optomai op'-tom-ahee; which is used for it in certain tenses; and both as alternate of 3708 to gaze (i.e. with wide-open eyes, as at something remarkable; and thus differing from 991, which denotes simply voluntary observation; and from 1492, which expresses merely mechanical, passive or casual vision; while 2300, and still more emphatically its intensive 2334, signifies an earnest but more continued inspection; and 4648 a watching from a distance):
appear, look, see, shew self.
